Which reaction among transcription factors greatly expands the diversity of regulatory factors that can be generated from a small number of polypeptides? a. Recombination b. Homodimerization c. Heterodimerization d. Trimerizastion
Homework Answers
The answer to the question-Heterodimerization
Heterodimerization is formed by two different proteins by the action of revese transcriptase which expands the diversity of regulatoryfactors.
