Answer:
Please find what occurs in the single nucleotide-pair substitution below
Explanation:
Single nucleotide-pair substitution is a type of point mutation as stated in this question. Point mutation is when one nucleotide base (single) is affected in the sequence. In this single nucleotide-pair substitution, ONE nucleotide base is substituted by another base.
For example, in a DNA sequence that reads: TAA GTC GGG, a mutated sequence affected by single nucleotide-pair substitution will read as follows: TAA GTC TGG. Note that in the last codon (GGG), a single nucleotide G has been replaced by another nucleotide T. Therefore, single nucleotide-pair substitution is said to have occur.
