Identify a, b and c. A(a) Elongation, (b) Termination, (c) Initiation B(a) Termination, (b) Elongation, (c) Initiation C(a) Initiation, (b) Termination, (c) Elongation D(a) Initiation, (b) Elongation, (c) Termination

Correct option is B. (a) Initiation, (b) Termination, (c) Elongation (a) A sigma factor is a protein needed for initiation of transcription in bacteria. It is a bacterial transcription initiation factor that enables specific binding of RNA polymerase (RNAP) to gene promoters (b)Rho factor is a prokaryotic protein involved in the termination of transcription. Rho-dependent termination occurs when the rho protein disassociates (c) Translation elongation is simply the ribosome travelling down the message, reading codons and bringing in the proper aminoacyl tRNA’s to translate the message out to protein. So the correct answer is "B".
