Define a mutation and explain how mutant forms are identified.

Expert Solution
Step 1

Any alternation in the sequence of nucleotide in the genome of any organism is known as mutation. Mutation arises due to error in replication, meiosis, mitosis, or due to damage such as by the radiation exposure. Mutation may also be caused by the deletions or insertion of DNA segment. The mutation caused by the insertion and deletion can affect the cells at gene level.
