The effect on the cells that are treated with an agent which caused the removal of cap from messenger RNAs (mRNAs). Concept introduction : After transcription, pre-mRNA is synthesized and further modified before translation in the cytoplasm. This is called the RNA processing and it includes the modification of mRNA ends and RNA splicing . A modified guanine (7-methyl guanine) group is added to the 5′ end of the mRNA chain with the help of the capping enzymes. This is known as the 5′ cap . At the 3′ end of the eukaryotic mRNA chain, adenine groups (poly-A tail) are added by poly (A) polymerase enzyme. This is known as the polyadenylation .

Q34. mRNA decay (breakdown) can play an important role in controlling protein abundance. Which of the following scenarios correctly describes a relationship between mRNA decay and protein abundance? A. A decrease in transcription with an increase in the rate of mRNA decay can result in increased protein abundance. B. An increase in transcription with an increase in the rate of mRNA decay can result in no change in protein abundance. C. An increase rate of protein synthesis but failure to form an apoprotein can be explained by a decrease in mRNA decay. D. None of the above

Q. Deletion of a single AT base pair from codon number 4 can cause a frameshift mutation in a protein-coding gene. Which of the following additional mutations will restore the reading frame back to “normal” such that the original stop codon will still function? (Note that the amino acid sequence will not necessarily be restored back to normal). Adding a base pair into each of the next two codons. Adding a GC base pair back in where the AT pair was deleted. Adding one base to the next codon and deleting one base from the one after that. Deleting a base pair from each of the next two codons. A. 1,2 and 3 B. 1 and 3 C. 2 and 4 D. 4 only E. All of 1,2,3 and 4 are correct
