Question

What is the approximate count of the total number of adenylate residues that are added to the 3’-end of the hnRNA during the process of tailing?

(a) 100-200

(b) 200-300

(c) 300-400

(d) 500-700

This question was addressed to me by my school principal while I was bunking the class.

This interesting question is from Molecular Basis of Inheritance topic in division Molecular Basis of Inheritance of Biology – Class 12

Answer 1

Right answer is (b) 200-300

For explanation I would say: During the additional process of tailing that is undergone by the hnRNA, adenylate residues are added to it. An approximate count of 200-300 adenylate residues are added to it at the 3’-end of the hnRNA.
