Summary Introduction

Mutation is nothing but a change in the genetic material. Mutations are different types that may occur rapidly or slowly. Sometimes, occurrence of second mutation can change the initial mutation this is referred as back mutation. Point mutation has the ability to reverse the mutation; it is termed as a reversion. Ames test is used to screen the chemicals that cause the mutation before it is applied to culture medium. It also helps to screen the potential carcinogens.
