Question
Chapter 7, Problem 4PIT
Summary Introduction
To explain:
Why a mutation in DNA sometimes causes protein function to change.
Concept Introduction:
Mutation is a sudden unpredictable change in the sequence of DNA. It causes alteration of DNA sequence. Mutation involves the substitution of DNA bases and deletion or insertion of DNA bases. It is also caused by mutagens such as exposure to certain chemicals and radiations.
