Summary Introduction
Introduction: Mutations refer to the alteration in the genome of an organism. Mutation is caused as a result of an error in the replication process of DNA. Mutations can be neutral, beneficial, or harmful for any organism. The alterations caused as a result of mutations is permanent in nature.
