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

Question

Quizplus · Accepted Answer

Terminal deoxynucleotidyl transferase (TdT) is the enzyme that adds nucleotides at the V-J junction during somatic recombination in B cells. This process is called N-nucleotide addition and it contributes to the diversity of the B cell receptor repertoire. DNA polymerase, RAG enzymes, and reverse transcriptase are not involved in N-nucleotide addition.
