46. In bacterial RNA synthesis, the function of factor ρ is to
a. Bind catabolite repressor to the promoter region
b. Increase the rate of RNA synthesis
c. Eliminate the binding of RNA polymerase to the promoter
d. Participate in the proper termination of transcription
e. Allow proper initiation of transcription

it is d- as it is p-dependent transcription, am I correct ?

dd

D...Rho factor

46. The answer is d.Bacterial DNA contains stop signals, some of which require ρ protein. This has been demonstrated by examining the synthesis of mRNA in the presence and absence of ρ protein. In the absence of ρ protein, longer RNA molecules are often synthesized. This would seem to indicate that mRNA length can be controlled by the cell. In addition,antiterminator proteins are needed to allow certain genes to be properly
expressed. Mammalian mechanisms for transcription termination, and the likely presence of factors regulating termination, are not yet characterized.
