Chapter 7, Problem 3TMW

Summary Introduction

To determine:

The reason behind the fact that the changes in $\text{RNA}$ sequences resulting from poor transcription are not as deleterious to an organism as changes to $\text{DNA}$ resulting from mutations.

Concept introduction:

Gene is defined as the basic unit of heredity. It is basically a sequence of nucleotides in the $\text{DNA}$ (deoxyribonucleic acid) that codes for functional proteins. In the expression of genes, $\text{DNA}$ is first transcribed into $\text{RNA}$ (ribonucleic acid) and then, this $\text{RNA}$ is translated into proteins. The proteins are responsible for the proper functioning of the cell.
