Question
Chapter 29, Problem 13CONQ
Summary Introduction
To review:
Meaning of molecular clock. Relation of this concept with the neutral theory of evolution.
Introduction:
Mutations are the changesthat occur in the structure of DNA (deoxyribonucleic acid) by addition, deletion or substitution of base pairs which, changes the reading sequence of the DNA. The mutations formed could be useful, harmful or neutral.
