Q. Which is the initial step in $m$RNA maturation process?
A) Polyadenylation
B) 5’ capping
C) Splicing
D) Endonucleolytic cleavage
Explanation
Messenger RNA ($m$RNA) acts as a template for protein synthesis. It is produced by DNA with the help of process called transcription by RNA polymerase-II. The 5’ end of the $m$RNA is modified by capping and the 3’ end is modified by polyadenylation.
