Which of the Following Processes Accounts for the Tremendous Variation

Question

Which of the following processes accounts for the tremendous variation in antibody structure?
A) RNA editing
B) Site-specific recombination
C) Integrase activity
D) Physiological adaptation
E) Hot spots of mutation in the immunoglobin genes

Accepted Answer

Site-specific recombination, also known as V(D)J recombination, is the process that generates diversity in antibody structure by rearranging variable (V), diversity (D), and joining (J) gene segments in B cells.
