Diversity in variable regions of L and H chains is generated by
A) selective proteolysis of pre-immunoglobulin proteins.
B) synthesis of multiple transcripts in each lymphocyte.
C) the splicing together of several V genes within the pre-mRNA.
D) gene rearrangement during cell differentiation.
E) None of the answers is correct.

Question

Quizplus · Accepted Answer

Gene rearrangement during cell differentiation is responsible for the diversity in the variable regions of light (L) and heavy (H) chains in immunoglobulins. This process allows for the vast array of antibodies that can be produced by the immune system.
