LIFE SCIENCE

Detailed explanation-1: -In biology, and especially in genetics, a mutant is an organism or a new genetic character arising or resulting from an instance of mutation, which is generally an alteration of the DNA sequence of the genome or chromosome of an organism.

Detailed explanation-2: -Mutations can be of many types, such as substitution, deletion, insertion, and translocation.

Detailed explanation-3: -Mutations result either from errors in DNA replication or from the damaging effects of mutagens, such as chemicals and radiation, which react with DNA and change the structures of individual nucleotides. All cells possess DNA-repair enzymes that attempt to minimize the number of mutations that occur (Section 14.2).
