6. Evaluation Of Glucosylceramide Synthase ( Gcs )
Abstract
Glucosylceramide synthase (GCS) is an enzyme that catalyzes the first step in the biosynthesis of
glucosylceramide (GlcCer)–related glycosphingolipids (GSLs). In the present report we have used
atom–based 3D–QSAR method to analyze the structural aspect on a series of iminosugar derivatives
as potent inhibitors of glycosylceramide synthase. In this approach the experimental dataset was
divided into training and test sets and the model was chosen based on randomized trial distribution
which has high correlation factors. A ligand–based pharmacophore and atom–based 3D–QSAR
studies were carried out on a set of 65 inhibitors of GCS. After the QSAR studies, a five–point
pharmacophore with two hydrogen bond acceptors (A), two hydrophobic group (H) and one ring
aromaticity (R) was obtained. The pharmacophore hypothesis yielded a 3D–QSAR model with good
partial least square statistics results. The training set correlation has these partial least square factors
(R2=0.92, SD = 0.178, F = 843.9, P = 1.12e–15). The test set correlation has these partial least
square factors (Q2 = 0.25, RMSE = 0.665, Pearson–R =0.54).
After the QSAR studies, docking study is being carried out. The docking study will reveal the
binding orientation of the active ligands on the protein which will be completed in BTP–phase II.
The result for QSAR and docking studies will provide structural characteristics of the active ligands
and also give detailed information about binding features which can useful

Computational biology became popular during the 1970's when the price of computers decreased
and they were easier to use and more readily available. Subsequently, this new technology was
introduced primarily to store and manage data that was produced through genomic research. This
then resulted in investigations to be completed in shorter amounts of time, which lead to larger
investigations, leading to more data being produced. Thus, bigger and better computers were needed
to manage the data that was generated. Hence, bioinformatics was used to create tools, algorithms
and databases, which enabled comprehensive management of data. Therefore, as more and more
data is being produced, the need for more powerful computers are needed in order to manage the
data. Furthermore, due to large amount of data being generated, larger databases are required and
more powerful tools are needed to manage and store the data.
The proteins play a key role in the biological function and their studies make possible to understand
the mechanisms that occur in many biological events. The human genome project enabled the
emergence of proteomics. Proteomics is the large scale study of proteins, particularly the functions
and structure of different proteins. The field of bioinformatics has had a significant effect in
proteomics, as it has introduced new algorithms to handle large and heterogeneous data sets.

The discovery of transformation by Frederick Griffith in Streptococcus pneumonia has played an
important role in how we are now able to introduce plasmid DNA molecules into cells.
Transformation is the uptake of DNA molecules released from the donor cell by the recipient cell. It
is one of the three ways bacteria are able to exchange genetic material. In Griffith's experiment he
introduced mice to two different forms of S. pneumonia, one smooth, pathogenic and encapsulated
and the other rough, nonpathogenic and noncapsulated (Snustad, 193). The mice were injected with
live rough strain and heat killed smooth strain. The deaths of the mice lead Griffith to conclude that
some genes of the killed smooth strain were transformed to the rough strain and the bacteria became
encapsulated and pathogenic, therefore leading to the death of the mice (Snustad, 193).
Plasmids are small circular DNA molecules. They are not essential for survival of the host bacteria.
Some carry genes that allow resistance to antibiotics (Anderson). Plasmid pUC18 is a circular DNA
molecule. It contains portions of the E. coli Lac Z gene, which encodes for the first 146 amino acids
of β – galactosidase. E. coli contains the Lac Z gene, which encodes β – galactosidase . The E. coli
Lac operon digests lactose. Once E. coli is transformed with pUC18, complementation occurs. E.
coli produces active β –galactoidase. The active β –galactoidase hydrolyzes the substrate, X gal ,
which is located on the agar plates.

Image Analysis When I was in 6th grade my family went on a trip to Paris France. While there we
were able to explore the city and visit many well–known places such as the Eiffel Tower, Louvre
and a royal palace called Versailles. The Versailles was originally built by a Louis XIII in 1623 as a
hunting lodge. In the years to come the building went through a few big expansions. After Louis
XIII died his son Louis XIV obtained Versailles and used it as his main residence and for the seat of
the government of the Kingdom of France. Also, the Versailles had enough rooms to be used for
most of the courtiers to stay there. My family and I were able to take a tour of the palace. While I

24. Diffusion Of Osmosis And Diffusion
Osmosis and diffusion are two important processes in the human body that help in the functioning of
cells and homeostasis, or maintaining balance within the body. Osmosis is the movement of water
from a higher concentration to a lower concentration, and its purpose is to maintain stability
between a solvent (water) and a solute. Diffusion is the movement of solutes down their
concentration gradient, toward a lesser concentration of solutes, in order to pass a membrane, such
as the lipid bilayer of the plasma membrane (Tortora and Derrickson 2012). Diffusion requires no
energy and is affected by many different aspects including heat, causing the reaction to occur at a
more rapid rate, the size of the particle, and the amount of space in which the diffusion must cover
(Tortora and Derrickson 2012). Osmosis is a form of diffusion that is more so for water, and both
require no energy. The phospholipid bilayer of the cell membrane is a protective barrier against
foreign materials that could harm the cell. The membrane is what is defined as selectively permeable
(Tortora and Derrickson 2012) because it only allows certain materials get into it, while keeping
others from moving out. The bilayer of the membrane has hydrophilic heads, which work well with
water, and hydrophobic tails, which repel water. This difference in the head and tails is what causes
only certain materials to be able to enter the membrane without help. Materials that can get in are

BIOSCI 751 – Molecular Plant Microbe Interaction
Evolution of plant pathogens
Introduction: Plant and microbial interactions are present right from the establishment of land plants.
The plants have co–evolved with the microbes since then (Gehrig et al., 1996). A microbial
interaction with the plant can have both positive and negative effects on the plant. Due to this, it has
gained high agronomic importance in today's plant science research (Stacey et al., 1996).
Plant Immune System: A pathogen in order to invade the host plant should pass through the various
plant immune system. The plants lack the adaptive immune system and have only the first line of
defence. Plants have Pathogen Recognition Receptors (PRRs) that recognize the Pathogen
Associated Molecular Patterns (PAMPs). This triggers the PAMP–triggered immunity (PTI). PTI
can halt the pathogen from further colonization by activating the disease resistant R protein. In
response to the host immunity some pathogens (for example bacteria) are capable of producing
effector proteins that will enhance the pathogen virulence. These effectors can disrupt the PTI and
induce Effector–triggered susceptibility (ETS). Plants have special receptors called Nucleotide
Binding–Leucine Rich Repeats (NB–LRRs) that can recognize the effector proteins specifically.
This results in the Effector Mediated Immunity (ETI). The ETI results in the Hypersensitive

I. Introduction
A. Attention Getter: Have you ever wanted to learn how to make a balloon animal?
B. Credibility: My interest in balloon animals came from a Christmas present from my four–year–
old niece. I started to watch YouTube and found videos by Michael Floyd as the most informative
and easy to follow.
C. Audience Relevancy: Learning how to make balloon animals is cheap, entertaining, and can be
shared with other people.
D. Thesis: Making balloon animals is a fun and interesting hobby.
E. Preview of Main Points: Today, I will explain balloon inflation and tie–off, measuring, and
twisting.

You will first pinch the balloon, then wrap the end around your first two fingers. Next, thread the
slack behind the beginning of the balloon and through your fingers. Now pull your fingers out of the
loop while holding on the lip of the balloon.
Transition: You will notice that I did not blow the balloon all the way up. I left about four finger
widths at the end.
B. Main Point Two: The measurement of inflated to the uninflated balloon is important throughout
the balloon animal process.
1. Measuring with your fingers helps to make your balloon animal come out in the correct
proportions.
2. You will leave about four finger widths uninflated because as you twist, it will push air into the
end of the balloon and fill it up.
3. I have practiced the balloon dog quite a bit, and have learned if you don't have proper
measurements then your dog can come out with a tail as long as its body.
Transition: Now it is time to twist!
C. Main Point Three: The actual twisting of the balloon is what makes the shape of the animal.
1. I came across some handy tips on a website called Iamnotaclown.com. One of those tips is to

43. Investigating The Rate Of The Red Water
The aim of this experiment is to observe and record the rate of the blue water in the dialysis tube
diffusing into the beaker containing different concentrations of salt over 20 minutes to see what
effect the concentrations of salt has on the rate of diffusion. The hypothesized of this experiment is
that the blue water in dialysis tube 3 will have a faster rate of blue dye diffusing into the salt water in
beaker 3. Beaker 1 will have the slowest rate of blue dye diffusing from the dialysis tube into the
salt water and beaker 2 will result in a colour in–between beaker 1 and 3. This is because the
concentration of salt in the beaker is higher than the water in the dialysis tubes so the salt water will
go into the dialysis tube while the blue water in the dialysis tube will diffusion into the beaker. This
experiment was performed by measuring out the same amount of water into each of the 3 beakers
and adding different amounts of salt to each one to change the concentration. 3 dialysis tubes
containing water and 3 drops of blue dye were tied at one end, then tied at the other using cotton
thread before placing them one each into the different concentrated beaker cotton tied end facing
down. After 20 minutes the results were observed and recorded into the results table. The finishing

47. Amplification Of Exons 2 And 4
Amplification Of Exons 2 and 4 To Detect Mutations In The HFE Gene Of Human DNA That Leads
To Iron Overload Causing Hemochromatosis
Introduction
The HFE gene, that causes the disease officially known as hemochromatosis, is found on the short
arm of chromosome six (Dostalikova–Cimburova et al., 2012). This HFE gene codes for a protein
that is found on the surface of liver, intestinal, and immune cells (D'Alessio et al., 2012). The HFE
protein interacts with many other proteins to cooperatively regulate the amount of iron present in the
body. The HFE protein regulates a very important protein called hepcidin. Hepcidin is the main trans
membrane protein that uses hormones to regulate iron in the body (Van Dijk et al., 2008).
When there ... Show more content on Helpwriting.net ...
The second major mutation of the HFE gene is the G845A nucleotide change in exon 4, which alters
the availability of the RsaI restriction sites (Barton et al., 2005). This is because a substitution is
made for the amino acid sequence C282Y in the protein (Trifa et al., 2012).
The purpose of the laboratory experimentation is to screen human genomic DNA for mutations in
the HFE gene, which are linked to hereditary hemochromatosis (Bates et al., 2008). This is
important because by amplifying the exons 2 and 4 within the HFE gene the single nucleotide
mutations will be detected and analyzed to better understand the cause of hemochromatosis. The
mutations of main focus as mentioned previously are the C187G nucleotide change within exon 2
and the G845A nucleotide change within exon 4. These are the main focus because they directly
alter the shape and function of restriction sites necessary for regulation of iron in the body. The
experimentation was completed using common techniques of PCR amplification, restriction digest,
and gel electrophoresis.
Materials and Methods
An important step in detecting the single nucleotide changes within the HFE gene that causes
hemochromatosis is to first use the process of Polymerase Chain Reaction (PCR) amplification to
amplify specific parts of exons 2 and 4. In the PCR amplification specific primers were used
independently for each exon 2 and

49. The Experiment On Sarophaga Crassipalpis
The experiment was done on Sarophaga Crassipalpis, a species that enters a period of
developmental/reproductive inactivity called diapause to avoid unfavorable environmental
conditions, regulated by neuroendocrine system in insects. The experiment was performed under
both nondiapause and diapause conditions. During the rearing stage, nondiapause conditions for the
flesh fly pupae were put under long day conditions of 15 hours light and 9 hours dark in 25 degree
Celsius temperatures. Diapause conditions were under short day conditions of 12 hours light and 12
hours dark at that same temperature. Resulting offspring were same light conditions at 20 degrees
Celsius. The total protein was prepared from brains of 25 diapause day 1 pupae as well as 25
nondiapause pupae day 2, then the proteins were extracted during the 5th, 15th, and 25th day after
diapause entrance. The proteins were put back into a protein extraction buffer, then put through
sonication on ice, a one freeze thaw cycle and centrifugation at 14,000 x g at 4 degrees Celsius. The
nuclear protein was prepared by the brains from the nondiapausing and diapause pupae being put
into a hypotonic buffer. The phosphorylated protein was prepared by the collecting samples that

This theory was formulated in 1970 and is one of the most recent on the topic of gel electrophoresis.
The National Academy of Science states, "The behavior of macromolecules in gel filtration and gel
electrophoresis may be predicted from Ogston's model for random mesh work of fibers. This model
has been generalized to apply to non–spherical molecules and to several gel types. The theory
defines conditions for optimal separation and optimal resolution in gel electrophoresis and gel
filtration" (Unified Theory for Gel Electrophoresis and Gel Filtration). There are a few components
that compose a gel electrophoresis chamber. First of all, there is a chamber used to contain the gel.
The gel used in my experiment will be made from agarose. In order to create an electric field, there
are positive and negative electrodes attached to a power source. My experiment will use alligator
clips as the electrodes and nine–volt batteries as the power source. A buffer solution, in this case a

53. Bacteria And Its Effects On Bacterial Populations
Often in prokaryotes like bacteria, they contain plasmids which are small double stranded rings of
extra DNA. Most of these plasmids contain a small amount of genes which replicated by themselves
rather than with the DNA in the cell. These plasmids could be beneficial or a detrimental to the
bacteria. For the beneficial side, plasmids contain products for toxins that can go on to make their
host immune to that of the toxin along with many infectious diseases have been cured by plasmids
as antibiotic resistances. The world today has seen an increase in antibiotic resistance and due to this
there is an increase in the amount of antibiotic genes in bacterial populations. When an antibiotic is
present in a bacterial cell, they will have an advantage when compared to other bacteria that do not
contain the antibiotic which will help them survive better in their respective environments.
Antibiotics are defined as "a medicine that inhibits the growth of or destroys microorganisms." They
do this by attacking the structure of the bacteria and destroying it within the body. Destroying the
bacteria can come in many different ways though. For one instance, the antibiotic will block the
bacteria's growth and reproduction by preventing the cell to multiply by blocking certain nutrients
that the cell would need to divide and reproduce. Another way the antibiotic can fight against the
bacteria is by destroying the cell wall of the bacteria causing it to die. These antibiotics can be

These tools give useful insight of information regarding the nature of target–ligand interactions,
which consequently predict molecular models which are further used for the lead discovery and
optimization. Ligand–based designing approaches are based on the information about structure of
the active ligand which can interact with biological targets. The efforts for the designing of the novel
drug molecule is based on the concept known as molecular similarity; compounds with high
molecular structural resemblance with pre–existing ligands, are more likely to have similar
pharmacological activity profiles. This approach is considered an indirect methodology as it is
usually followed in absence of the 3–D structure of the target or if the target is unknown or cannot
be predicted.
There are a number of ways to screen a small molecule library in order to identify key pattern
present in a known active molecule or a set of them. The most common and simplest approach is the
use of molecular descriptors or physicochemical properties. Molecular features, such as electronic,
steric and hydrophobic properties, are obtained from practical experiments or theoretical

Changes are being made to refine the genetic engineering techniques that are being used such as the
use of less invasive procedures and less creation of large quantities of animals warranting for less
animals exposed to harmful procedures, because out the ones that are created only so many survive
the genetic engineering procedures or actually have the wanted outcome.
There are also concern with the some of the outcomes of experimenting with genetically modified
animals especially with the transplant of animal organs into humans as this may cause catastrophic
results being that all human pandemics have been cause of animal viruses that adapted to replicate in
humans. Also experimenting with the genes of animals raises ethical dilemmas as some animals
have been genetically modified to carry mutations associated with human diseases and often suffer
the same symptoms of these conditions like humans.
My personal view on this matter of genetically modified animals is that if they are used for a good
purpose such as medicine for humans and other animals than this is a good cause.

Explain the effect that increasing the Na+ Cl– concentration has on osmotic pressure and why it has
this effect. How well did the results compare with your prediction?
Increasing the Na+ Cl– concentration in the left beaker while keeping the size of MWCO at 20
would result in an increase in osmotic pressure (Run No.2). This was because the high concentration
of Na+ Cl– in the right side of membrane gives a increased force to water (in left beaker) to move
towards the solution with the highest concentration of solutes. Therefore, there was an increase in
osmotic pressure.
However, when the membrane was changed to from 20 MWCO to 50 MWCO, the Na+ Cl–
molecules were able to diffuse through the membrane, the equilibrium would be reached and no
osmotic pressure was generated. If the concentration of Na+ Cl– of both size are equal, the osmotic
pressure would be zero.
I obtained the results from the experiment supported my predictions because as the the concentration
Na+ Cl– was increased from 5 mM to 10 mM (by adding more Na+ Cl–), the osmotic pressure also

(Kasturiratne et al. 2008). The negative impact of this could be alleviated by the creation and
production of a low–cost, human–compatible universal antivenom. Lethal Toxin Neutralizing
Factor, henceforth LTNF, is a substance that has been isolated from opossum (Didelphis virginiana)
serum, liquid component of blood. LTNF can neutralize nearly all venoms, by a mechanism not yet
understood, including those never before encountered by the opossum (Menchaca Perez 1981,
Shier 2008). The active site of LTNF has been isolated into a 15 amino acid–long ... Show more

Currently, antivenoms are produced by injecting non–lethal doses of the venom into other animals,
typically large mammals, and collecting the antibodies produced in response (Domont et al. 1991).
In contrast, our project produces LT–15 using genetically manipulated E. coli. There are immense
benefits to our project. Primarily, the benefits derive from the use of LT–15 as a universal antivenom
in medical settings. With LT–15, medical facilities can carry fewer venom–specific antivenoms and
more LT–15, reducing storage costs. Additionally, LT–15 could be used as an initial or booster
antivenom, for when the active venom cannot be immediately identified. Furthermore, use of LT–15
could decrease the per–unit cost of antivenom. Because production of antivenom has high fixed
costs but low variable costs, economies of scale exist and the average cost falls as production
quantity rises. Since LT–15 could be used universally, we anticipate a large demand for it, leading to
a lower cost for per–unit of LT–15 than for each antivenom it replaces (Chen et al. 1995). Finally,
the use of an E. coli to produce antivenom would nearly eliminate the allergic reactions many
patients experience with antivenoms produced in large mammals (Lipps 2000). Current antivenom
production yields a large quantity of animal serum with many antibodies, only some of which are
venom–specific. In order to achieve adequate levels of specific antivenom in the bloodstream, a

Genetic Modification Organisms: Testing on Oats, Tortilla Chips, and GMO+ samples Nichole
Wong
Abstract:
In this lab, we tested for the presence of genetically modifications within foods. Specifically, we
investigated genetically–modified oats, genetically–modified tortilla chips, and a genetically
modified GMO+ sample. I hypothesized that the oats would have tested negative for GMOs, the
tortilla chips would have tested positive for GMOs, and the GMO+ sample would have tested
positive for GMOs. During testing, my group mashed the oats and tortilla chips in separate tubes
with InstaGene liquids and water. We then proceeded to perform PCR to multiply the number of
genes for experimentation with PMM and GMM (plant master mix and gene master mix, which both
held the primers used for DNA replication). The samples were finally placed into an electrophoresis
chamber (referred to as a gel box) with loading dye and went under DNA electrophoresis. The
results showed that GMOs were used in the harvesting of oats, the manufacturing of tortilla chips,
and the preparation of GMO+ samples. Moreover, because the sample for the plant DNA in the oats
was destroyed and the tubes that held plant DNA in tortilla chips, GMOs in tortilla chips, and GMOs
in GMO+ samples were mixed up, there is doubt as to whether or not we received accurate results.

82. Using The Latest Trends Of Business Processes
Abstract
The purpose of this paper is to identify and to enumerate the benefits and disadvantages of adopting
the latest trends, especially advancements in technology, in small–scale businesses. A brief summary
of a scenario involving non–fictional characters is included to depict similar real–world conundrums
faced by entrepreneurs. This paper first illustrates the benefits of incorporating the aforementioned
trends into small–scale businesses, and then moves on to list and to discuss its disadvantages. Lastly,
the paper weighs the pros and cons of using the latest trends of business processes. All arguments
provided in the paper are based on the depicted scenario. Other assumptions made by the author of
this paper are included to provide a more elaborate and thorough discussion of the case in study.
Case Study: Going Against the Modern Tide Matt and Grace own a small supermarket in a rural
town. Their target demographics are the growing population of slightly computer–literate elderly in
the town as well as the students of a nearby private liberal arts college. They also don 't experience
any competition from large chain stores because of their remote location. After attending the
Chamber of Commerce meeting, Matt suggested undergoing a project to build a website for their
supermarket in order to boost their sales as well as to make their business more competitive. He was
adamant about adopting the latest trends in business process in order to keep their business
