Detailed explanation-1: -The correct answer is: Substitution.

Detailed explanation-2: -Substitution, as related to genomics, is a type of mutation in which one nucleotide is replaced by a different nucleotide. The term can also refer to the replacement of one amino acid in a protein with a different amino acid.

Detailed explanation-3: -Mutations can be of many types, such as substitution, deletion, insertion, and translocation.

Detailed explanation-4: -Such a substitution could: change a codon to one that encodes a different amino acid and cause a small change in the protein produced. For example, sickle cell anemia is caused by a substitution in the beta-hemoglobin gene, which alters a single amino acid in the protein produced.
