Chapter 20, Problem 4CONQ
Summary Introduction
To review:
The two molecular mechanisms that give rise to gene conversion. These both mechanisms take place in the break of the double-stranded model of DNA (deoxyribonucleic acid).
Introduction:
DNA is genetic material of almost all living organisms. It transfers genetic information encoded into its nucleotides from one generation to another. The model of DNA was first discovered by Francis Crick and James Watson. It is a double-stranded structure, which consists of two chains that run in the opposite direction.
