CSIR JRF/NET Life Sciences December 2016 Booklet Questions + Keys + Explanations Part C

Answer – 2 Statement A is wrong. Isotopes differ on neutrons.

Answer – 4 Statements A and C are correct.

Answer – 3 Statements A and D are correct. The four types of beta turn are distinguished by the Φ, ψ angles of residues i+1 (2) and i+2 (3).

Answer – 4 In Figure, b or d have less activity due to ammonium sulfate precipitation. Ammonium sulfate precipitates protein and after centrifugation, protein settles in the pellet. The supernatant show a little activity.

Answer – 2

Answer – 1 The enzyme and substrate complex is more stable when compared to free enzyme alone. With Protein X, the curves shows better activity compared to Protein Y.

Answer – 4 Band 3, Glycophorin and GPCR are integral membrane proteins, difficult remove by 5M NaCl salt treatment.

Answer – 2 LAMP1 (lysosomal associated membrane protein) in present in Lysosomes. LC3 Puncta is present in Autopahagosome. In autophagy, Autopahagosome fuse with Lysosome and degrades its contents. The Protein A-GFP should always colocalizes with LAMP1, which is present in Lysosomes. Since, Bafilomycin inhibits formation of lysosome, the Protein A-GFP will co-localizes with LC3, which is present in L autopahagosome.

Answer – 3 The inhibitor A acts like uncoupler. Actually CSIR gives wrong in the options. It is NADPH Oxidation not NADP+ reduction.

Answer – 2

Answer – 1 G1 phase cells will have more radioactivity, because they enter S phase immediately.

Answer – 3 Cefalexin is a beta-lactam antibiotic of the cephalosporin family. It is bactericidal and acts by inhibiting synthesis of the peptidoglycan layer of the bacterial cell wall. As cefalexin closely resembles d-alanyl-d-alanine, an amino acid ending on the peptidoglycan layer of the cell wall, it is able to irreversibly bind to the active site of PBP, which is essential for the synthesis of the cell wall.

Answer – 3

Answer – 3 Because of mutation to Pre-mRNA gene, snRNP is not going to bind, so it not retained in the nucleus.

Answer – 4 Basal level translation observed with CHP, which is leaky allows polysome formation thus translation.

Answer – 3 CpG islands are typically unmethylated in promoters for housekeeping genes.

Answer – 3

Answer – 3 The helicase loading complex inhibited by early G1 CDK in G1 phase, so high levels of CDK activity.

Answer – 2 In trypanosomes, all RNAs are processed by the concerted action of trans-splicing and polyadenylation. In transsplicing, a leader sequence is donated to all mRNAs from a small RNA molecule, the SL RNA.

Answer – 1

Answer – 3 Hormone Receptor X and H, shows high Activity with Hormone X and less activity with receptor Y.

Answer – 1 Case A, B and D leads to less apoptosis.

Answer – 4

Answer – 3 The levels of high p53 and low cyclin D in treated cells .

Answer – 4

Answer – 1 β-catenin not produced by Spemann organizer.

Answer – 4 First, Driesch had demonstrated that the prospective potency of an isolated blastomere (those cell types it was possible for it to form) is greater than its prospective fate (those cell types it would normally give rise to over the unaltered course of its development). According to Weismann and Roux, the prospective potency and the prospective fate of a blastomere should be identical. Second, Driesch concluded that the sea urchin embryo is a “harmonious equipotential system” because all of its potentially independent parts functioned together to form a single organism. Third, he concluded that the fate of a nucleus depended solely on its location in the embryo – From Developmental Biology by Gilbert.

In graph, a and b showing maximum recovery. Statements iii and iv can have maximum diffusion.

Answer – 4 Statement C is wrong. Because CSIR asking proteins function inside of plant cell.

Answer – 1 Since 0.5 M Urea does not denature protein, so there is no increase in florescence. But in Florescence figure, b [0.5 M Urea) shows more fluorescence than native protein (a).

Answer – 1

It is not α-phosphate but γ-phospate group added to the DNA at 5’ end.

Answer – 4

gene '0' for ronftning resistance .to ult-stress. The selection mmer genes. used for both the transformation experiments were different. Ti'ansgenic plano obtained following the retransfontUltion experiment were screened for MItstress resistance and single copy events were identified by Southerp hybridil.ation. These single copy events were self-pollinated. In the event of the two T-DNAs (containing the A and B transgcnes) getting integrated in unlinked locations in all the transgenic planb, the phenorypic ratios amQiig the T I progeny Would be: I. 1 (!'ungal resistant + Salt-stress rcsistant): I (Fungal risi:nant) . 2. I (t'uRS,1resistant); 2 (Fungal rtsi:>tant ... Salt-stress resistant): I (Salt-stress resistant) 1. 1 (Salt-stfe55 resi:nant): I (Fungal resistant) 4. t (Fungal resistant): !-(Salt-stress resistant):1 (Fungal resistant + Salt sltess resistant)
