Which of the following does not contribute to the large variety of antigen-binding specificities found among the immunoglobulins?
A) Recombination between different versions of V, D, and J segments
B) Somatic hypermutation
C) Imprecise joining of immunoglobulin segments
D) Retrotransposons

Question

Quizplus · Accepted Answer

Retrotransposons have no known involvement in the generation of antigen-binding specificities of immunoglobulins. Recombination between different versions of V, D, and J segments, somatic hypermutation, and imprecise joining of immunoglobulin segments all contribute to the large variety of antigen-binding specificities found among immunoglobulins.
