Quizplus · Accepted Answer

Terminal deoxynucleotidyl transferase (TdT) is the enzyme responsible for adding N nucleotides during V(D)J recombination, which is the process that creates diverse antigen receptor genes in B and T cells. TdT adds random nucleotides at the junctions between gene segments, increasing the variability of the resulting antigen receptors. The other enzymes listed are involved in other aspects of DNA metabolism, but not specifically in adding N nucleotides during V(D)J recombination.
