Some Giant Sulphur Bacteria are so large as to be visible to the naked eye. Nonetheless, they have been very difficult to cultivate and classify. Why? Solution Cultivate Grow very slowly. Metabolism is based on lithotrophic utilization of sulphide oxidation coupled to nitrate reduction which is gives poor yields. In natural environments they grow in gradients where one end of filament is sulphide rich, the other end nitrate rich. Difficult to simulate in the lab. Classify Morphology has been used, but this is not linked to phylogeny. 16S rRNA hard to amplify due to containing an intron.

Describe the different kinds of motion that can occur. Solution Every sound we hear, every photon of light that hits our eyes, the movement of grass blown by the wind and the regular beat of the tides are all examples of waves. They are all around us. Visible, physical wave*s such as those we see when a rock is thrown into water are what many people think about when they first began to think about waves. These waves have distinct properties specific to their type but also exhibit characteristics in common with more abstract waves such as sound waves and light (electromagnetic) waves. Below is an interactive illustration that explores particle and energy motion for the three wave types listed above. Once you have reviewed the illustration and accompanying text, test your understanding of these concepts with the wave type At the simplest level, waves are a disturbances that propagate energy through a medium. Propagation of the energy depend on interactions between the particles that make up the medium. Particles move as the waves pass through but there is no net motion of particles. This means, once a wave has passed the particles return to their original position. As a result, energy, not matter, is propagated by waves. Different types of waves exhibits specific characteristics. These characteristics are used to distinguish between wave types. Orientation of particle motion relative to the direction of energy propagation is one way waves are characterized. There are three categories: A second way that waves are characterized is by the types of matter they are able to travel through.Electromagnetic waves (including light) can move through a vacuum. Physical waves require matter through which to propagate. Physical waves are further distinguished by the phases of matter through which they can move. Longitudinal waves can pass through liquids and gasses while transverse waves require a material to be solid to propagate..

right now I am using a l293d chip to control my DC motor which is 6 volt. I was wondering if there was a python code that can control the motor based on temperature. I am using tmp102 ic2 temperature sensor also. Solution L293D IC generally comes as a standard 16-pin DIP (dual-in line package). This motor driver IC can simultaneously control two small motors in either direction; forward and reverse with just 4 microcontroller pins (if you do not use enable pins). Some of the features (and drawbacks) of this IC are:.

How are macromolecules transported across the nuclear envelope? Describe the structure that regulates nuclear membrane permeability. Solution The transportation of molecules in and out of the nucleus is controlled by the nuclear pore complex(NPC). Small molecules move through the nuclear membrane with ease but for macromolecules like proteins, RNA etc, they require an association with transportation factors like importins, karyopherins and exportins. Proteins that need to be carried into the nucleus have nuclear localization signals (NLS) which bind to the importins. NLS is a sequence of Amino acids which act as a tag. They are mostly hydrophilic but hydrophobic sequences have also been documented. Nuclear Import: Importins bind to the macromolecule to be transported in the cytoplasm itself. The complex then interacts with the NPC and passes through the channel. Once inside the nucleus, it interacts with Ran-GTP and the importin dissociates from the macromolecule it was carrying. Then the importin-Ran-GTP complex is transported to the cytoplasm where it is separated from importin by the Ran Binding Protein (RanBP). After being separated from importin, GTPase activating protein(GAP) binds with Ran-GTP and induces hydrolysis of GTP to GDP. The Ran-GDP produced binds with the nuclear transport factor(NUTF2) and then returns to the nucleoplasm. Inside the nucleus, Ran-GDP interacts with guanine nucleotide exchange factor(GEF) which replaces GDP with GTP and Ran-GTP is born again to repeat the cycle. Nuclear Export: In the nucleoplasm, exportin binds the macromolecule to be transported outside the nucleus and Ran-GTP. The complex diffuses through the pore to the cytoplasm where it dissociates. Ran- GTP binds to GAP and hydrolysis resulting in Ran-GDP. Ran-GDP is returned to the nucleus where it exchanges its ligand for GTP. Nuclear Pore: The nuclear pore complex is made of proteins called nucleoporins. Around 50% of nucleoporins contains solenoid protein domains (alpha or beta-propeller fold) and the rest might have both as separate structural domains. Each NPS has about 456 individual protein molecules with 30 distinct nucleoproteins. These are highly flexible proteins that lack an ordered secondary structure..

Consider two point sources separated by a distance of 10 meters. The longitudinal waves emitted from the two sources have the wavelength of = lm. The velocity of the wave is 2m/sec. What is the frequency f and the period T? Solution Frequency=Velocity/wavelength =(2m/sec)/1m =2 Hz Time period= 1/Frequency =1/2 =0.5 sec a) Amplitude at C =0.1+0.1=0.2 m (Since waves are in phase) b) Waveform will be at same amplitude that is 0.2 m c) If the distance between the points A and B is changed. The waves interfere distructively. Therefore, amplitude is zero. That is 0.1-0.1=0 d) If source A is delayed by 0.5 sec The path difference is= 2(0.5)=1 m Therefore, waves interfere constructevely. The wave amplitude at point C is., 0.1+0.1=0.2 m.

Describe the repair mechanisms used during DNA replication. Solution DNA like any other molecule can undergo a variety of chemical reactions. Because DNA uniquely serves as a permanent copy of the cell genome, however, changes in its structure are of much greater consequence than are alterations in other cell components, i.e RNA’s and Proteins. Mutations can consider the incorporation of incorrect bases during DNA replication. And also, various chemical changes occur in DNA either spontaneously or as a result of exposure to chemicals or radiation. Such damage to DNA can block replication or transcription, and can result in a high frequency of mutations—consequences that are unacceptable from the standpoint of cell reproduction. To maintain the integrity of their genomes, cells have therefore had to evolve mechanisms to repair damaged DNA. DNA repair mechanism can be divided into two general classes: (1) direct reversal of the chemical reaction responsible for DNA damage, and (2) removal of the damaged bases followed by their replacement with newly synthesized DNA. The rate of DNA repair is dependent on many factors, including the cell type, the age of the cell, and the extracellular environment. A cell that has accumulated a large amount of DNA damage, or one that no longer effectively repairs damage incurred to its DNA, can enter one of three possible states: 1. an irreversible state of dormancy, known as senescence 2. cell suicide, also known as apoptosis or programmed cell death 3. unregulated cell division, which can lead to the formation of a tumor that is cancerous The DNA repair ability of a cell is vital to the integrity of its genome and thus to the normal functionality of that organism. Direct reversal Cells are known to eliminate three types of damage to their DNA by chemically reversing it. These mechanisms do not require a template,the types of damage they counteract can occur in only one of the four bases. Such direct reversal mechanisms are specific to the type of damage incurred and do not involve breakage of the phosphodiester backbone. The formation of pyrimidine dimers upon irradiation with UV light results in an abnormal covalent bond between adjacent pyrimidine bases. The photo reactivation process directly reverses this damage by the action of the enzyme photolyase, whose activation is obligately dependent on energy absorbed from blue/UV light (300–500 nm wavelength) to promote catalysis. The second type of damage, methylation of guanine bases, is directly reversed by the protein methyl guanine methyl transferase (MGMT), The third type of DNA damage reversed by cells is certain methylation of the bases cytosine and adenine. Excision Repair mechanisms Single strand damage: When only one of the two strands of a double helix has a defect, the other strand can be used as a template to guide the correction of the damaged strand. In order to repair damage to one of the two paired molecules of DNA, there exist a number of excis.

Describe the current state of the human beta globin gene family and the processes that were involved in generating it from a single ancestral globin gene. How do the members of the gene family differ and how do these differences relate to their expression and function? How does the human beta globin gene family differ from the beta globin gene families in other vertebrates? What do these differences imply about the evolution of this gene family in different species; are the same processes that shaped the human gene family also at work in the other species and if so why are the gene families different in the other species? What differences in the beta globin genes are found among the current human population and what are the genetic consequences of these differences? Solution human -globin locus are composed of five gene, that are located on short chromosome number 11, This locus also contains the delta, gamma-A, gamma-G, and epsilon globin. Expression of all genes are controlled by a single locus control region, and all beta genes are differentially expressed during development. Duplication + divergence of ancestral gene is the major process involve in generation of beta gene form single ancestral globin gene. Human beta globulin gene come under gene family because of gene family is set of various similar gene that form by duplication of single original Gene & almost similar biochemical function. Gene family member are different in several way 1. arrangement of genes directly reflect to differentiation of their the expression during development. For proper Functioning required another alpha globin for complete function for example- Hemoglobin protein is made of two alpha and two beta polypeptide are encoded by different gene. Globin genes are similar in structure Each gene encoded similar but different protein. 2. Expression of gene is regulated in the embryonic erythropoiesis by the many transcription factors like [KLF1] and that which is associated with upregulation of the adult and another [KLF2] which are vital to expression of the embryonic hemoglobin. beta-globin gene are clustered & work as unit of gene regulation, embryo --> express epsilon, fetal --> express gamma, adult --> express beta (and delta) Gene order-position-location- important for regulation of gene. the human beta globin gen family different form beta globin gene family in vertebrate- 1.Polyploidy occurs more often in plant genome than in animal one or at least vertebrate genomes. 2. loss of intron- first & third intron only two intron found in vertebrate hemoglobin & myoglobin genes. Thecentral intron was lost before the divergence of annelids & arthropods and absent in all the vertebrate hemoglobin and myoglobin genes. Intron loss has in different organisms & there is extreme example of the total intron loss in arthropod Chironomus. 3. major gene duplications in vertebrate globin’s. evolution of this gen family in difference species- Gene families are the groups of the.
