Chapter 9, Problem 14RQ
Summary Introduction
To review:
The six different types of DNA repair mechanisms and the DNA repair mechanisms that contribute to mutation.
Introduction:
The collection of processes by which the cell identifies and corrects damage to the DNA (deoxyribonucleic acid) molecule before it becomes a heritable mutation is called DNA repair. Microorganisms have a variety of molecular tools to repair the damaged DNA molecule.
