Final answer:
The DNA recombination process that produces diversity in the antigen-binding sites of immunoglobulins is called V(D)J recombination. It involves the random recombination and splicing of gene segments encoding the variable (V), diversity (D), and joining (J) regions of immunoglobulin genes to generate a wide range of antibody molecules. Each B cell typically has a unique antigen-binding site due to the rearrangement of these gene segments.
Step-by-step explanation:
The DNA recombination process that produces diversity in the antigen-binding sites of immunoglobulins is called V(D)J recombination. This process occurs during the maturation of B cells in the bone marrow. It involves the random recombination and splicing of gene segments encoding the variable (V), diversity (D), and joining (J) regions of immunoglobulin genes to generate a wide range of antibody molecules. Each B cell typically has a unique antigen-binding site due to the rearrangement of these gene segments.
