The adaptability of the system is achieved by localized somatic mutations and an irreversible recombination of antigen receptor gene segments.llows a small number of genes to generate a vast number of dich are then uniquely expressed on each indiviual lymphocyte.
The adaptability of the system is achieved by localized somatic mutations and an irreversible recombination of antigen receptor gene segments. This mechanism allows a small number of genes to generate a vast number of different antigen receptors, which are then uniquely expressed on each indiviual lymphocyte.
