Mutation that only changes in single base in a sequence of DNA

Answer 1

A point mutation is a type of mutation that involves a change in a single nucleotide base in a DNA sequence. This can result in the substitution of one nucleotide for another, the insertion of an extra nucleotide, or the deletion of a nucleotide. Point mutations can lead to changes in the amino acid sequence of a protein, which can affect the protein's structure and function.
