Summary Introduction

To review:

The kind of mutations that are present in DNA (deoxyribonucleic acid) sequences when comparing the given sequence $\text{5'-ATGGGACTAGATACC-3'}$ with the following:

A. $\text{5'-ATGGGTCTAGATACC-3'}$

B. $\text{5'-ATGCGACTAGATACC-3'}$

C. $\text{5'-ATGGGACTAGTTACC-3'}$

D. $\text{5'-ATGGGACTAAGATACC-3'}$

Introduction:

Point mutations are a common type of mutation in which a lone nucleotide in a DNA sequence undergoes a change. There could either be addition of a nucleotide, deletion of a nucleotide or conversion of one nucleotide into another that could lead to changes in the amino acid coding sequence or the mRNA (messenger ribonucleotide) transcript which, when translated, generates a different polypeptide chain than before.
