Chapter 20, Problem 20.74QP

Interpretation Introduction

Interpretation:

The terms deletion mutation and the insertion mutation have to be defined.

Concept Introduction:

In messenger RNA, a nucleotide triplet that codes for a specific amino acid is termed as a codon. A codon is significant because if a single base is changed in the codon it can change the amino acid composition or may even result in no protein synthesis at all.

Such changes in the nucleotide may be either of the forms of point mutation, insertion mutation, or deletion mutations.
