1. Describe two constraints which limit the maximum size of a cell. 2. In what 2 ways do eukaryotic cells overcome some of the limitations on cell size to allow them to be larger than prokaryotic cells? 3. List the following structures in order from smallest to largest: Protein Bacterial cell Atom Human muscle cell Ribosome Nucleus Human epithelial cell 4. What features are common to both eukaryotic and prokaryotic cells? Solution 1. A)Cells are capable of taking resources in and expel waste and energy through skinny, pores and skin-like membrane surrounding it. As the volume of the cell will increase in size, it need to accumulate and expel more materials; but, due to the fact the volume grows but there\'s a limit to the quantity of diffusion which could take resources into or out of a cell. B)The nucleus of a cell is basically a small sphere (nucleus)within a bigger sphere(cell).Because the nucleus need to be large to govern a big cell,the nucleus is also liable to the hassle of surface to extent ratio. This limits the dimensions of the nucleus, which in turn, limits the size of cell. 2.The small size of prokaryotes permits ions and molecules that enter them to diffuse to different elements of the cell. Similarly, any wastes produced within a prokaryotic cell can quickly diffuse out. This isn\'t always the case in eukaryotic cells, which have evolved exceptional structural adaptations to enhance intracellular transport. 3. Structures so as from smallest to largest: Atoms Protein Bacterial cell Ribosomes Nucleus Human muscle cells Human epithelial cells 4.Similarities between eukaryotic and prokaryotic cells are: A)Cell membrane Both have lipid bilayer that\'s an association of phospholipids and proteins that acts as a selective barrier between the inside and outside environment of the cell. B)Genetics: Eukaryotic and prokaryotic cells each have deoxyribonucleic acid (DNA) .This genetic material had to alter cell feature and encodes into the progeny. C)Ribosomes Both eukaryotic and prokaryotic cells have ribosomes to provide protein for the cells. D)Cytoplasm The cytosol is one essential aspect of the cytoplasm in each prokaryotes and eukaryotes – this jelly like liquid incorporates numerous ions, molecules and organelles. Therefore, it is also the site of many metabolic reactions, inclusive of protein synthesis..

A precise definition of globalization is difficult, because globalization is a process which removes economic, social and cultural boundaries of nation states. Discuss this process. Do you think that globalization is a win-win situation for all countries? You may argue in favor of or against this view. Solution Globalization is a process of interaction and integration among the people, companies, and governments of different nations, a process driven by international trade and investment and aided by information technology. Globalization is defined as a process which integrates the world economy. It is a process which removes economic, social and cultural bindings. Globalization is a complex and multifaceted phenomenon. It is the process of internationalintegration as a product of exchange of world views, products, ideas and other aspects of culture in which worldwide exchange of national and cultural resources occurs in the process.Many factors contributed for the growth of globalization major being advancement intransportation and communication. The current wave of globalization is nothing but the resultof Schumpeterian evolution in technology along with interaction of many actors at differentlevels of the economy. Globalization means different for different people. For some it createspositive political, economic and technological progress. For few globalization is hegemonic andantagonist to local and national economies. Globalization has changed situations in such amanner that power of state is determined by power of firm. If the goal of globalization wasmore liberal exchange of goods, services, labor, thoughts etc which in later stages would makeworld uniform, then there is no space for identity. There are positive aspects for cultural globalization that will foster diversity when there is aninteraction between boundaries leads to mixing of culture which results in pluralization. Thereis condensation and differentiation on ideas which brought many unique aspects of certainculture into lime light. The concept of glocalization has gained popularity which would help inimproving standards of life, without hampering the local tradition. Diversity itself has become aglobal value now which is been promoted by international organizations and movements. Globalization is not a debate aboutdivergence or convergence, but it is a dialectical process which can both integrate and fragmentalong with creating both winners and losers. I do not think that globalization is a win win situation for all countries and even if it is at least winning amount is different for each country. not all countries are gaining equally from globalization and some countries especially labour abundant countires like India are at loss as there is no freedom of human capital transfer in globalization process. Globalization is thus an ongoing syndrome. Globalization is not only about interplays betweenlocal, regional, national and global scales, but also about the interconnectedn.

Pnc po,B F2 no,C MO, E Solution BJT in active mode means EB Junction is forward biased and CB juction is reverse biased. Since EBJ is forward biased, the depletion width is smaller thean CBJ depletion width (which is reverse biased). Let us consider the electrons injected from the emitter into the base. These electrons will be minority carrier in the p-type base regrion. Because the base is usually very thin, in the steady state the excess minority carrier concentration in the base will have an almost straight-line profile. This tapered minority-carrier concentration profile causes the electrons injected into the base to diffuse though the base region toward the collector. The Collector-Base juction is reverse biased so the minority carrier concentration profile can be constant in collector..

a.) Describe a difference between the RNA polymerases of eukaryotes and prokaryotes. b.) Which of the following enzymes are known to be involved in the replication of DNA in bacteria? Check all that apply. DNA Polymerase I RNA Polymerase II DNA Polymerase II RNA primase ligase Solution Thanks for the question Prokaryotic transcription occurs in the cell cytoplasm and, in prokaryotes, both transcription and translation happen simultaneously. Eukaryotic transcription occurs in the cell nucleus and, in eukaryotes, transcription and translation differ in space and time. RNA polymerases are an essential requirement for transcription. Eukaryotic cells are more complex than bacteria in many ways, including in terms of transcription. Specifically, in eukaryotes, transcription is achieved by three different types of RNA polymerase (RNA pol I-III). These polymerases differ in the number and type of subunits they contain, as well as the class of RNAs they transcribe RNA pol I transcribes ribosomal RNAs (rRNAs), RNA pol II transcribes RNAs that will become messenger RNAs (mRNAs) and also small regulatory RNAs RNA pol III transcribes small RNAs such as transfer RNAs (tRNAs). Replication of DNA in bacteria requires DNA Polymerase I DNA Polymerase II RNA primase ligase Regards.

In the past several years the number of harmful algal blooms has been dramatically increasing. In fact, a recent bloom of Microcystis aeruginosa, known for its secretion of the hepatotoxin microcystin, has threatened the water supply of Lake Erie cities such as Toledo and Cleveland. An EPA friend wishes to study this species in order to prevent such blooms, and in so doing, finds significant heterogeneity in gene expression in clonal algal cells (same species, identical DNA) in the same environment! There is one order of magnitude of variation in certain transcription factors and two orders of magnitude of variation in lipid content. Recognizing your expertise your friend asks you for advice: Is this result reasonable or was this likely due to experimental error? How would one go about testing and explaining the results? Provide an answer to your colleague. Solution To study gene expression , since a long time, Microarray technology is being used in order to study more number of genes in a single experiment. This is then interpreted using significance analysis of transcriptomic data, but the disadvantage here lies that it would ignore gene dependence structure. Therefore , along with microarray technology for studying heterogeneity, FAMT would allow to capture gene dependence as a factor of computation of results. FAMT: Factor Analysis for Multiple Testing (FAMT) : is defined as simultaneous tests under dependence in high-dimensional data. It takes into account various factors to give high throughput data and accurate results. In FAMT, effects of the experimental conditions and the nuisance variability on gene expression, due to technical errors and other known or unknown effects, can be easily separated. The factors can be distinguished and interpreted using graphics. I am not aware of what protocol was followed by my colleague. Neither am I aware if the interfering signals were cancelled by the protocol followed. So rather, I would suggest to perform microarray for testing gene heterogeneity and interpreting the results using FAMT, so as to eliminate all sorts of interfering signals/ factors and also handling errors , if some. Results can be interpreted later after elimination of any error possibilities..

What is the difference between a short and long branch? Solution long branch is a form of systematic error whereby distantly related lineages are incorrectly inferred to be closely related. LBA arises when the amount of molecular or morphological change accumulated within a lineage is sufficient to cause that lineage to appear similar (thus closely related) to another long-branched lineage, solely because they have both undergone a large amount of change, rather than because they are related by descent. Such bias is more common when the overall divergence of some taxa results in long branches within a phylogeny. Long-branches are often attracted to the base of a phylogenetic tree, because the lineage included to represent an outgroup is often also long-branched. The frequency of true LBA is unclear and often debated. Although often viewed as a failing of parsimony-based methodology, LBA can result from a variety of scenarios Long branch effects distort maximum.

This is a Physiology qquestion. Describe the two general meanings of the term membrane, as used in biology. Which usage indicates layers of cells and which indicates layers of molecules? Solution Answer: Two general meanings of the term \"membrane\" in biology are to describe the structure of cell membrane that is permeable to some molecules but not all molecules. Second meaning of a \"membrane in biological cell\" is to protect inner cytoskeleton with organelles. Membrane is made of phospholipid bilayer in which one is hydrophilic region and another is hydrophobic region. The phsopholipid layers indicates layers of lipids and membrane proteins whereas the layers of cells is mainly due to \"membrane associated cell adhesion molecules\" These three macromolecules together to form a complex phospholipid bilayer in which periplasmic proteins are distributed in a mosaic manner. The large fluid mosaic structure is formed from these macromolecules composed of phospholipid bilayers with protein channels for the transport of organic & inorganic nutrients including trace metal. Normally, the essential aspects of these structures composed of \"porins, protein channels, integral proteins” that dictate their function for the selective permeability, diffusion of nutrients across the membrane into & out of the cell finally to attain homeostasis Fluid mosaic model describes that two-dimensional liquid layer of cell membrane where proteins distributed like mosaic model in the phospholipid bilayer. This model mostly accepted by biologists Role of the protein molecules in this model cell membrane layers are membrane extracellular protein domains in connection to the lipid bilayer membrane. Membrane phospholipids are the molecules with hydrophillic polar heads towards the solvent such as water whereas hydrophobic tail located towards the center of the layer and this bilayer formed by micelles, as fatty acids possess one polar associated with another nonpolar head. Cell membrane possesses a property known as selective permeability. Cell membrane consists of phopholipid bilayer that also include several of the transmembrane proteins, ion channels etc. Small, nonpolar molecules with hydrophobic nature diffuse more easily into the cell membrane. Similarly, proteins interact and assemble themselves to form several layers of structures in our body..
