What are the roles of TFIIIA, TFIIIB, and TFIIIC?
What will be an ideal response?
Ans: TFIIIB is the major transcription factor for RNA polymerase III, allowing it to bind near the transcription start point of a gene. Both TFIIIA and TFIIIC are assembly factors; they bind downstream of the gene's start point to assist in the binding of TFIIIB.
