Chapter 20, Problem 20.53QP

Interpretation Introduction

Interpretation:

The term poly (A) tail has to be defined.

Concept Introduction:

The sequences that do not encode to any amino acids are termed as introns, and the transcript that consist of important protein coding regions and introns are collectively called exons. Thus, after the RNA splicing, the exons come together. They are then capped at the 5′ end with the first nucleotide present in the transcript along with a poly (A) tail and the RNA transcript thus constitutes the mature RNA that is ready for the translation process.
