Which enzyme inserts nucleotides at the V-J junction to add further diversity?

Question

Quizplus · Accepted Answer

Terminal deoxynucleotidyl transferase, or TdT, is the enzyme responsible for adding random nucleotides to the V-J junction during V(D)J recombination. This process is called N-nucleotide addition and increases the diversity of the B and T cell receptor repertoire. DNA polymerase, RAG enzymes, and reverse transcriptase are not involved in this specific step of V(D)J recombination.
