Somatic hypermutation additional antibody diversity is generated in rearranged variable region gene units by a process called somatic hyper mutation somatic hyper mutations occur at a frequency of 10-3 per base pair per generation.
The antigen-binding properties of the antibody reside entirely in the amino-terminal portion of the molecule, termed the variable domain structurally, the combining site specificity is determined by the amino-acid residues within 6 short lengths, 3 each in the heavy and light chains, of unusually variable sequence.
