Question
Chapter 20, Problem 3QSDC
Summary Introduction
To review:
To determine whether the selfish DNA (deoxyribonucleic acid) hypothesis is correct or not.
Introduction:
DNA is the genetic material which functions as the genome for the transfer of information from one generation to another. DNA is a double-stranded helix-shaped molecule, which has a phosphate group and a deoxyribose attached with the nitrogenous bases.
