Explanation:
Detailed explanation-1: -With base substitution mutations, only a single nucleotide within a gene sequence is changed, so only one codon is affected (Figure 1).
Detailed explanation-2: -Substitutions result in a change that only affect one codon. This is known as a point mutation.
Detailed explanation-3: -Substitution 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.
