Question

50. Which is not related to regulation of gene activity? A. Transcription factor binding close to the promoter regions. B. SAM binding to mRNA. C. Alterations in mRNA conformations by Trp availability. D. All of these. E. None of these. 17. Which describes the effect of insulin on the liver? 8. Among the many fatty acids: _________ series as an especially important precursor of eicosanoids such as thromboxane and prostaglandin. They are important for scar healing and uterus contraction but also cause unnecessary inflammations and pains. The two main enzymes involved in production of eicosanoids are lipoxygenase and , which are important drug targets. 20. All nucleotides are synthesized as mononucleotides. Which amino acid is not used for the synthesis of purine bases? 22. The enzymes involved in the synthesis of pyrimidine nucleoside monophosphates are under multiple regulations. Which is not involved in the regulation?

Explanation / Answer

1. Transcription factor binds to the promoter regions or closer to the promoter regions. SAM is a compound that binds to the mRNA for regulating the gene expression.

Hence the correct option is E.

2. Insulin promotes the glycogen synthesis thus decreasing the lipid and glucose pathways.

Hence the correct option is C.

3. Eicasonoids are signalling molecules. Arachidonate is a eicasonoid responsible and important factor for prostglandin and cyclooxgynase is a class of eicasonoid.

Hence the correct option is D.

4. Glycine contributes most to the purine production thus followed by the asparatic acid and glutamine.

Hence the correct option is B.
