Chapter 21, Problem 21.56E

Interpretation Introduction

Interpretation:

The reaction that is used to excise introns from $\text{hnRNA}$ is to be predicted. The reaction that is used to join the exon segments together is to be stated.

Concept introduction:

A segment which is located on $\text{hnRNA}$ and cannot transfer genetic information is known as intron. A segment which is located on $\text{hnRNA}$ and can encode single part of the mature RNA after eliminating the introns is known as exon.
