Chapter 15, Problem 4TY
Summary Introduction
Introduction: Those factors which cause the mutations are known as mutagens. The mutagens can be derived from the environment such as UV lights or x-rays. The influence of high amount of mutagen on an organism can lead to the formation of thymine dimer, which is very harmful to the organism.
