Which of the following correctly states the functions of the rough endoplasmic reticulum ? lipid metabolism, cholesterol synthesis, and synthesis of the lipid components of lipoproteins absorption, synthesis, and transport of fats. storage of calcium ions synthesis of the cell\'s membranes Solution As per the given options rough endoplasmic reticulum functions are :- 2) Absorbtion, synthesis and transport of fats & 4) Synthesis of cell membranes Generally, the eucaryotic cell contains two types of endoplasmic reticulum i) Rough Endoplasmic Reticulum. Rough Endoplasmic Reticulum why named as rough means it contains ribosomes on it so, the surface of the reticulum looks rough. The main function of the rough ER is protein synthesis due to the ribosomes. Rough ER through the membrane contact sites contact with the other organells allowing the transfer of lipids and other small molecules. The intestinal cells, pancreatic cells, which involves in the absorption process contains more rough ER why because the proteins synthesized by the Rough ER involved in the intracellular transport of resynthesized lipids.So the rough ER indirectly helps in the absorption process. ii)Smooth Endoplasmic Reticulum:- Due to the absence of ribosomes it looks smooth so named as smooth ER. The main role is lipid metabolism, and synthesis of carbohydrates and steroid harmones and storage of calcium ions So, in the given question the first option(Lipid metabolism, cholesterol synthesis, synthesis of lipid components of lipo proteins) indicates smooth Endoplasmic Reticulum functions 2nd option Absorbtion, synthesis and transport of fats indicates Rough Endoplasmic Reticulum functions 3rd Option Indicates(Storage of Calcium ions) smooth Endoplasmic Reticulum functions 4th Option is synthesis of cell membrane, For this function the main role of rough Endoplasmic reticulum is during the lipid transport the replenishment of new membranes is done by the morphological change of rough endoplasmic reticulum involved..

What is isomerism? How many kinds are there? Define each kind and explain with examples? What is isomerism? How many kinds are there? Define each kind and explain with examples? Solution The process of isomerism involves the isomers .These are basically defined as the molecules which have the same molecular formula but they usually possess a different arrangement of the atoms in space. They are of two types: 1.Constitutional isomers :They are defined as the compounds in which the various atoms are connected or bonded in a different manner .They are also called as structural isomers 2.Stereoisomers:On the other hand ,they are the compounds which differ on the basis of orientation in space.They are of two types a)Enantiomers :They are the compounds which are usually a mirror image of one another and thehese mirror images are also non-superimposable b)Diastereomers :They are isomers which are not mirror images of one another.Moreover these compounds are non-superimposable. They are of two types: cis and trans ->Cis-isomers are the isomers which usually contain atoms which are oriented on the same side of a bond. ->On the other hand the Trans-isomers are the compounds that have atoms oriented on opposite sides of a bond.

The D flip-flop tracks the input, making transitions with match those of the input D. The D stands for \"data\"; this flip-flop stores the value that is on the data line. It can be thought of as a basic memory cell. The Q output always takes on the state of the D input at the moment of a rising clock edge. (or falling edge if the clock input is active low). 2. A register is a group of binary cells suitable for holding binary information. A group of cascaded flip flops used to store related bits of information is known as a register. 4. A counter is a device which stores (and sometimes displays) the number of times a particular event or process has occurred, often in relationship to a clock signal. Each pulse applied to the clock input increments or decrements the number in the counter. 5. An adder, also called summer, is a digital circuit that performs addition of n-bit binary numbers. 6. A multiplexer (or mux) is a device that selects one of several analog or digital input signals and forwards the selected input into a single line. A multiplexer of 2n inputs has n select lines, which are used to select which input line to send to the output..

Two sources of radio waves (call them 1 and 2) are separated by a distance d along the a-axis in the plane, and emit sinusoidal waves of the same wavelength A and frequency f in the N (+y), S (-y), E (+x), and W (-x) directions. Suppose that we want to arrange the sources to broadcast a signal in the E direction, but not the W. Can this be accomplished? If so, how? In not, why? Solution both the sources are identicle and emit in all direction N,S,E,W. by introducing a path difference equal to half wave length the waves will have distructive interference and signal is destroyed but this happens in both the direction E nd W equally. Hence it is not possible to arrnge the sources such that we have signal only in E nd not in W, the only way to achieve this is to shield the source in W direction or put reflectors in W direction so that all W signal is reflected back to E.

TB is a major worldwide disease with new cases arising at an alarming rate, What factors can account for this and what lays behind the trend of multidrug resistant strains of mycobacterium? please cite reference. Solution Tuberculosis is caused by mycobacteriam tuberculosis. TB is one of the most common cause of death due to infection of the mycobacteriam species.various factor have been found to develop resistance against M. tuberculosis. resistance means simply afterwards that drug potency in terms of pharmacological response will be decresed gradually and at certain level it will not active against the strain. There are two types of resistance 1. natural resistance and second is aquired resistance. natural resistance is found on wild strain. multidrug resistance is the phase in which strain is not responsive against primary line therapy of disease. factor which induced resistance gene factor In a recent year study suggest that the patient who shows the presence of HLA -DRB1 13 and HLA-DRB 1 14 has two fold risk to develop resistance against strain.(Park et al.) Incomplete and inadequate mangment Review of literature suggests that the most powerful factor of MDR-TB is a history of treatment of tuberculosis(diagnosis). TB patients get treated with DOTS regimens not only through the Revised National Tuberculosis Control Programme (RNTCP), but also receive treatment from private medical doctors. Irregular, incomplete, inadequate treatment is the commonest mean of acquiring drug resistant due to improper mangment of drug mostly organism develop the resistnacce against drug eg. use of single drug to treat tb is the fetal cause to develope resistance against organisms.it may be due to ignorance. anothe common error in prescription error it may like additions syndromes. Inadequate treatment compliance : the change over form has complied a significant effece in development of drug resistance it was observed that only 44 per cent of the patients receiving short-course treatment (n=2300) and 36 per cent of those receiving standard chemotherapy (n=1000) completed 81 per cent or more of their treatment. Noncompliance with prescribed treatment is often underestimated by the physician and is difficult to predict. On the other hand, certain factors such as psychiatric illness, alcoholism, drug addiction and homelessness do predict noncompliance .The drug defaulter, just like placebo reactor is not a consistent or readily identified person demographic factors such as ,sex, age, marital status,socio-economic status and education levelhave not been found to correlate with the degree of compliance..

7. How did printing technology impact literacy and education? Solution 7. How did printing technology impact literacy and education? Printing technology impacted literacy and education. Printing transformend the world and made very important changes. Previously people don\'t have much access to information. They used to write. So, the books are expensive. In 15th century Johannes Gutenberg invented a printing machine and made it available to world. Not all are rich enough to buy hand written books till 15th century. As books are expensive so does literacy. To learn to read and write, need to refer to books. When this printing machine came to availability, books became cheap and affordable. Then on wards the barrier of high cost had gone. Source of knowledge are hand written papers or books besides people. Information is not so much available. Again because of expensive things. When printing is available news papers came into picture and from then on people had one more source of knowledge which is cheaper. In this way printing technology impact literacy and education..

A geneticist Dr. O. Sophila discovers a new mutation that causes the flies to shake and quiver. She calls this mutation spastic (sps) and determines that spastic is due to an autosomal recessive mutation. She wants to determine if the spastic gene is linked to the gene for vestigial wings (vg) - also a recessive phenotype. She has true breeding stocks for each kind of mutations. She crosses a spastic fly with a vestigial wing fly and then uses the resulting F1 females in a testcross. She obtains the following F2 flies from the testcross: Spastic with normal wings 230 NonSpastic with vestigial wings 224 Spastic with vestigial wings 97 NonSpastic with normal wings 99 Are the genes that cause vestigial wings and the spastic mutation linked? Provide the rationale to your answer. What is the genotype and phenotype of F1 females? Annotate the genotype notation illustrates whether sps and vg alleles are in cis or trans arrangement to each other. What is(are) phenotype(s) of th Solution Answer: 3.1) Spastic (recessive) = s; Nonspastic (dominant)=s+ Vestigial wings (recessive)= v; Normal wings(dominant) = V ssVV (spastic fly) x s+ s+ vv (Vestigial wings)-----P sV s+v----------------------------gametes s+sVv (nonspastic, normal wing)---------F1 F1 X ssvv------------Test cross.

Monohybrid crosses with incomplete dominance and co-dominance The red and white alleles for the snapdragon flower color gene exhibit incomplete dominance. When pink flowers were produced from red- and white-flowered parents, early geneticists thought this might represent \"blending inheritance, \" where the hereditary information from one parent melded with the information from the other. Use Punnett Squares to determine the phenotype ratios in snapdragon offspring from the following crosses, that show that blending inheritance is not an accurate way to characterize this situation. define the notation (letters) you will use: pink x pink (if blending inheritance were accurate, we would predict that all offspring would be pink) pink x red (if blending inheritance were accurate, we would predict that all offspring would be dark pink) Solution A cross between pink and pink flower plants. The genotype of pink flower plants would be Rr (R allele for red colour and r allele for white colour). A case of incomplete dominance. The gamete formation results in R and r genotypes And the offsprings will be red ,pink, white in the ratio of 1:2:1 respectively. All offsprings are not pink. There is segregation of alleles during gamete formation, that results in new combination of genes in tha offsprings. Here alleles for red and white colour were present in the parents and their offsprings also contains new combination of alleles. A cross between red and pink flower plants. The genotype red is RR and pink is Rr. The cross between the two results in red and pink flowere in equal ratio 2:2. Here the alleles were present for red and white colour in the parents RR X Rr. There is no occurance of blending inheritance, Here the concerned genes for red (RR) and white (rr) colour show incompletee dominance when come together in an organism and shows pink colour (Rr). This does not mean that it happens in all conditions, as the conditions are exceptional cases. Here the heterozygote (Rr) posses genes for both red and white colour and when self crossed results in new combination of genes due to their segregation during gamete formation and homozygous condition will be retained in some plants (RR and rr) that results in red and white flowers.RrRRRRrrRrrr.

In metaphase 1 of meiosis, the homologous chromosomes line up side by side along the equator so that (a) crossing-over (exchange of DNA regions) can occur between the homologous pairs and (b) the homologous chromosomes can be pulled to opposite poles during anaphase 1. In mitosis, by contrast, homologous chromosomes line up single-file along the equator. What benefits are derived from these two different ways that homologous chromosomes are positioned at metaphase in meiosis and mitosis? Solution The equatorial arrangement of chromosomes make the cell divisions to occur more symmetrically. This chromosomal alignment is the keyspot of metazoan cell divisions. The spindle fibers in both mitosis and meiosis relocate the metaphase plates if they are not properly arranged. Homologous chromosomes functions differently in both mitosis and meiosis. The homologous chromosomes in mitosis do not pair with eachother like they do in meiosis. They line up independently at the equatorial plate whereas in meiosis they occur in pairs. The chances of chromosomes to cross one another by mitotic recombination is very rare..

Gene frequencies for the ABO alleles vary geographically. For example the I^A allele makes up nearly 50% of the genes for blood type among Australian Aborigines, about 25% in Central Asian populations, and 0% in peoples native to South America. No blood type has sufficient selective advantage over another to explain these regional differences. From these facts, what can you infer about the history of our species Did humanity develop as a large and continuous population spreading out across the planet, or did we disperse while still living in small scattered groups Solution Based on the above data human population developed as small, some of them scattered into small groups and acclimatised to new geographical area. In each group some dominant blood alleles become predominant and become major allele in that population during course of time. This is the reason for differences in gene frequencies.
