B) Bringing various V, D, J gene segments together to form a functional gene encoding the variable region of an antibody
C) Molecularly "gluing" recombinant V, D, J gene segments together for transcription
D) Transcribing and translating recombinant V, D, J gene segments into protein
E) None of the above
