All of the following require 5′ capping except?
Correct Answer: tRNA of Alanine
Description: tRNA of Alanine does not require 5' capping. Capping process protects the 5' end of mRNA from the action of exonucleases and polyadenylation protects the 3' end of the mRNA. All mRNA, snRNA, and siRNA undergo this process, but tRNA are comparatively stable and do not require a capping at the 5' end. Reference: Harpers illustrated biochemistry 30th edition
