Cell Physiology: Discuss the ramifications of the Human Genome Project and the evolving definition of a gene based on expanding knowledge of the complexities of genome transcription. Solution Human genome project: Human genome project initially stated to examine the single nucleotide polymorphism among the human populations. The main goals are the type of genetic methods used predominantly to produce genetic maps of all human chromosomes finally sequencing the approximately three billion nitrogen base pairs within human DNA. Human genome project is useful to analyze the existence of genetic variants in dissimilar progeny. According to human genome project, NHGRI, \"trait is defined as the phenotypic feature i.e. mainly representing a specific encoding character of a gene in any organism. The ramifications of the Human Genome Project involve the gene transcription based on the \"genome annotation, genome evolution followed by segmental duplication\". These genomic alterations are going to trigger evolutionary aspects of changes in gene expression so that genomics and proteomics have meticulous importance in explaining complexities of genome transcription. This is because a majority of human genome is transposbale elements and only 1.5% of genome is going to code for proteins So that Genome is defined as the total genetic content of the organism including organelles, inside the chromosomes that represent that organism\'s genetic character. Intron is the noncoding nucleotide codons (A, G, C, U) on messenger RNA for any amino acid. It is produced through gene expression or transcription in the presence of RNA polymerase. It is removed through splicing by spliceosomes. Exon is the coding nucletode codons (A, G, C, U) on messenger RNA for any amino acid. It is produced through gene expression or transcription in the presence of RNA polymerase. It is not removed through splicing by spliceosomes. Haplotype: Accoridng to human genome project, NHGRI, a haplotype is the inheriting genetic material of DNA sequences (combinations of alleles) i.e. situated on the adjacent location of chromosomes of the organism. Epigenetics- inheritance phenomenon of human genome project: This explained by the following examples including genomic imprinting by which certain genes expressed in a parent-of-origin- specific manner. If the allele inherited from the father imprinted, thereby gene silenced, and only the allele from the mother expressed. A gene, which needed efficient placental growth to supply nutrients and its expression, is active from maternal allele and inactive of paternal allele. Proteomics methods are predominantly have been using by the researchers to analyze the evolving definition of a gene based on expanding knowledge of the complexities of genome transcription. This is done via the genomic wide sequencing analysis of horizontal gene transfer of bacterial evolution & intragenomic alterations in eukaryotes finally it is possible to deduce an evolutiona.

A complete set of chromosomes/genes inherited as a unit from one parent called genome. The entire genetic complement of a living organism. The total amount of genetic information in the chromosomes of an organism, including its genes and DNA sequences. The genome of eukaryotes is made up of a single, haploid set of chromosomes that is contained in the nucleus of every cell and exists in two copies in the chromosomes of all cells except reproductive and red blood cells. The human genome is made up of about 35,000 genes.

Molecular markers for measuring genetic diversity Introduction: The molecular basis of the essential biological phenomena in plants is crucial for the effective conservation, management, and efficient utilization of plant genetic resources (PGR). Determining genetic diversity can be based on morphological, biochemical, and molecular types of information. However, molecular markers have advantages over other kinds, where they show genetic differences on a more detailed level without interferences from environmental factors, and where they involve techniques that provide fast results detailing genetic diversity Comparison of different methods Morphological characterization does not require expensive technology but large tracts of land are often required for these experiments, making it possibly more expensive than molecular assessment. These traits are often susceptible to phenotypic plasticity; conversely, this allows assessment of diversity in the presence of environmental variation. Biochemical analysis is based on the separation of proteins into specific banding patterns. It is a fast method which requires only small amounts of biological material. However, only a limited number of enzymes are available and thus, the resolution of diversity is limited. Molecular analyses comprise a large variety of DNA molecular markers, which can be employed for analysis of variation. Different markers have different genetic qualities (they can be dominant or co-dominant, can amplify anonymous or characterized loci, can contain expressed or non-expressed sequences, etc.). Genetic marker The concept of genetic markers is not a new one; in the nineteenth century, Gregor Mendel employed phenotype-based genetic markers in his experiments. Later, phenotype-based genetic markers for Drosophila melanogaster led to the founding of the theory of genetic linkage. A genetic marker is an easily identifiable piece of genetic material, usually DNA that can be used in the laboratory to tell apart cells, individuals, populations, or species. The use of genetic markers begins with extracting proteins or chemicals (for biochemical markers) or DNA (for molecular markers) from tissues of the plant (for example, seeds, foliage, pollen, sometimes woody tissues). Molecular markers In genetics, a molecular marker (identified as genetic marker) is a fragment of DNA that is associated with a certain location within the genome. Molecular markers which detect variation at the DNA level such as nucleotide changes: deletion, duplication, inversion and/or insertion. Markers can exhibit two modes of inheritance, i.e. dominant/recessive or co-dominant. If the genetic pattern of homozygotes can be distinguished from that of heterozygotes, then a marker is said to be co-dominant. Generally co-dominant markers are more informative than the

The Role of Introns in Genetic Regulation ================================ Introns are sequences that interrupt open reading frames (ORFs) in RNA. Spliceosomal introns are exclusive of eukaryotic nuclear gene transcripts, are a complex of small nuclear RNAs (snRNAs) and proteins . Introns are crucial because the protein variety is greatly enhanced by alternative splicing in which introns take partly important roles. Changes in the exon-intron structure of a gene can also occur, including the loss or/and gain of introns. Intron loss is important aspect of gene structural variation and plays a vital role in gene evolution. This report focuses on the intron, its origin, classification, evolution, loss and gain, function, and the diverse roles of splicing and alternative splicing in human disease.

Why are animals like a snail, a clam and a squid, which all look very different, considered to be in the same phylum? Solution Animals of same phyla share maximum common characteristics of their reproductive, digestive, or nutrition, locomotion, habitat, morphology, body symmetry and other characters. Those characteristics evaluate with score on matching and animals of maximum resemblance score take under the same phyla. A new criterion is also use to set phyla, on the basis of genetic equality..

What is the difference between a secured bond and a debenture bond? Respond using at least one internet resource. Explain why a bond may sell at a premium. Solution The bonds are secured by the collateral assets i.e. the assets are pledged as security that if the company fails to pay the principle and the interest on the bond within stipulated time, the holders could discharge their debts by seizing and selling the company\'s pledged assets. The debentures are the debt security issued by a company which is not secured by any specified assets, but it denotes a general credit of the company. A bond can be sold at a premium when it offers a coupon rate that is higher than prevailing market interest rates. Therefore, the investors would pay more for the bonds if they are provided with a higher yield on the said bond. ===================================.

Using the Thin-lens equation: A 1/f = 1/p + 1/q. with equation: B L = p + q and q = p + d p = L - d/2 and q = L + d/2. Derive equation: C f = L^2 - d^2/4L. Explain mathematically why no image is formed if the object and image are separated by a distance that is less than 4f. Solution A. given: 1/f = 1/p + 1/q which gives f = pq/(p+q) p =(L - d)/2 and q = (L+d)/2 f = [(L - d)/2]*[(L + d)/2]/[(L - d)/2 + (L + d)/2] f = (L^2 - d^2)/4L B. u = object distance, v = image distance s = separation of object and image, f = focal length of the lens. 1/u + 1/v = 1/f 1/u + 1/(s - u) = 1/f (s-u+u)/(u*(s-u)) = 1/f fs = su - u^2 u^2 = (u - f)s s = u^2/(u - f) By differentiating it ds/du = ((u - f)(2u) - u^2)/(u - f)^2 = (u^2 - 2uf)/(u - f)^2 = u(u - 2f)/(u - f)^2 ds / du = 0 when: u(u - 2f) = 0 u = 0 or, for a real image, u = 2f. When u < 2f, ds / du < 0. When u > 2f, ds / du > 0. u = 2f is therefore a minimum. By same method v = 2f is therefore a minimum image distance. which means total separation 4f..

One of the citations MUST come from the class textbook (-10 point penalty points if this is not done), and NONE may be from ANY encyclopedia, including Wikipedia (-10 point penalty if this is done). For full credit, you must have three sources and at least three citations. You must also have a properly formatted reference section at the end of the paper. The paper’s in-text citations AND works cited section must conform to the format found in the examples from this website: http://www.chicagomanualofstyle.org/tools_citationguide.html (be sure to click on the Author-Date tab!). you must be very careful when they examine internet websites and provide at minimum the author/publisher, date published or accessed, and the title of the article or website. The URL should also be available. All written assignments must be typed, in 12-point font, and double-spaced. Solution 1.a,Those currently incarcerated: Incarceration in the United States is one of the main forms of punishment, rehabilitation, or both for the commission of felony and other offenses. The United States has the largest prison population in the world. 1.The number of people incarcerated in America quadrupled-from roughly 500,000 to 2.3 million people. 2.Today, the US is 5% of the World population and has 25% of world prisoners. 3.Combining the number of people in prison and jail with those under parole or probation supervision, 1 in ever y 31 adults, or 3.2 percent of the population is under some form of correctional control. b).Parole is the provisional release of a prisoner who agrees to certain conditions prior to the completion of the maximum sentence period.Most states have the ability to release prisoners on parole after they almost surely pose no threat to the public. c).I believe that convicted felons should be allowed to vote, indeed I believe they should actually be allowed to vot.

There is an area that has been classified, according to the IEC requirements, a being ‘Group IIA’. Compare this to something that has been classified, by the Americans or Canadians, as ‘Class I, Group A’. Which would be the most dangerous are of the two? Solution Among Group IIA and clasS I the GrouP IIA is dangerous. Group IIA contains flammable liquid ,combustible liquid and flammable gases. These are caused at the time of explosion which are dangerous. This produces high temperature which causes harmful to humans ,animals ,environment. It may releases some different gases in to earth which causes effect to environment and it may causes new health problems. This group IIA can mix with oxygen and pollute the air. Class I: It contains liquid ,vapour and flammable gas and acetylene. Which does not contains more pollution and effect when compared to Group II A. compare class I and Group II A Group IIA is dangerous and high tendency to mix with air..

Problem Definition Build a Date class and a main function to test it. Specifications Below is the interface for the Date class: it is our \"contract\" with you: you have to implement everything it describes, and show us that it works with a test harness that puts it through its paces. The comments in the interface below should be sufficient for you to understand the project (use these comments in your Date declaration), without the need of any further documentation. But of course, as always, you can ask us any questions you may have on Piazza. Note: Placing the error messages into the constructors like is not necessarily a good way to handle constructor errors, but until you learn about exceptions in CS 14, it\'s the best we can do. Private Member Functions The functions declared private above, isLeap, daysPerMonth, name, number, are helper functions - member functions that will never be needed by a user of the class, and so do not belong to the public interface (which is why they are \"private\"). They are, however, needed by the interface functions (public member functions), which use them to test the validity of arguments and construct valid dates. For example, the constructor that passes in the month as a string will call the number function to assign a value to the unsigned member variable month. isLeap: The rule for whether a year is a leap year is: (year % 4 == 0) implies leap year except (year % 100 == 0) implies NOT leap year except (year % 400 == 0) implies leap year So, for instance, year 2000 is a leap year, but 1900 is NOT a leap year. Years 2004, 2008, 2012, 2016, etc. are all leap years. Years 2005, 2006, 2007, 2009, 2010, etc. are NOT leap years. Output Specifications Read the specifications for the print function carefully. The only cout statements within your Date member functions should be: the \"Invalid Date\" warnings in the constructors in your two print functions Required Main Function You must use this main function and global function getDate as they are here. You may not change these functions at all. Copy-and-paste these into your main.cpp file and then add the Date class. Solution // Date.h #include #include #include #include using namespace std; class Date { private: unsigned day; unsigned month; string monthName; unsigned year; public: Date(); Date(unsigned m, unsigned d, unsigned y); Date(const string &mn, unsigned d, unsigned y); void printNumeric() const; void printAlpha() const; private: bool isLeap(unsigned y) const; unsigned daysPerMonth(unsigned m, unsigned y) const; string name(unsigned m) const; unsigned number(const string &mn) const; }; //Date.cpp #include #include #include #include using namespace std; #include \"Date.h\" // creates the date January 1st, 2000. Date::Date() { day = 1; month = 1; monthName = \"January\"; year = 2000; } /* parameterized constructor: month number, day, year - e.g. (3, 1, 2010) will construct the date March 1st, 2010 If any of the arguments are invalid (e.g. 15 for month o.

What would be their individual and collective roles and responsibilities? Solution If the lower-level managers are involved in implementing a better budgeting process, the players in the budgeting process would be top management, middle management and lower level management. They would be the people who look after the budgeting process. The collective role of the people involved is to acheive the budgeted results to the organisation as a whole and their respective roles. There responsibilities would include individually, they need to be aware of the results of their respective departments individually..

Could a poly-Ala sequence form a beta sheet? Why or why not? Solution Protein secondary structures are formed due to hydrogen interactions between amino acids present in linear polypeptide. Alfa helix and beta sheets are the typical secondary structures. Alfa helix formed due to intra chain hydrogen interactions and beta chains formed due to inter chain hydrogen interactions. In both cases hydrogen interactions play crucial role. The hydrogen interactions formed between partial charged atoms. Partial charged atoms exists due to dipole moment. Dipole moment observed in molecule with different electro negative atoms. Here alanine contain, a non ionic, hydrophobic side chain, that is Alanine. So it cannot form hydrogen interactions. So cannot form beta sheets.

Early on the morning of April 15, 1912, the RMS Titanic collided with an iceberg as she made her maiden voyage from Southampton UK to New York City USA. Although this British passenger liner was designed with advanced safety features including watertight compartments with remotely activated watertight doors, she only carried enough lifeboats for 1,178 people due to outdated maritime safety regulations. The ship\'s hull plates buckled inwards along her starboard side due to the collision, flooding five of her sixteen watertight compartments. 1,514 of the 2,224 aboard perished, making this sinking one of the deadliest commercial peacetime maritime disasters 1.Suppose that 30% of those onboard came onboard at Cherbourg. What is the probability (correct to three decimal places) that at most 4 of 10 randomly selected people onboard came onboard at Cherbourg? Solution We use binomial probability for this one. Using a cumulative binomial distribution table or technology, matching n = number of trials = 10 p = the probability of a success = 0.3 x = the maximum number of successes = 4 Then the cumulative probability is P(x <= 4 ) = 0.849731667 [ANSWER].

Discuss why ethnoarchaeology is so important in helping us understand different cultures. Solution Study of social organisation and other features helps to understand different cultures, We, all know that culture is , learned behaviour which has been socially acquired. Culture is the product of human societies, and man is largely product of his cultural environment. Culture is transmitted from one generation to another through learning process. Role of culture: It provides mechanisms and beheaviour which secure for an individual his personal and social survival. Culture stands for customs, beliefs,laws, religion, arts and other capabilities and skills acquired by man as a member of society. Cultural factors in health and disease play important role. Every culture has its own customs, some of which has very high influence on incidence of disease For example, cancer of lungs from smoking and cirrhosis of liver from drinking are results of abuse of widely claimed social habits. In India, chewing pan is associated with oral cancer So, that cultural factors are deeply involved in matters of personal hygiene, nutrition, immunisation, seeking early medical care , family planning, child rearing, disposal of refuse and excreta, outlook or health and disease.
