A gene that undergoes rho-dependent termination has a mutation in the rut site. How will this influence transcriptional activity?
A)Transcription will terminate normally as Rho termiantion relies on the rut site to enhance termination; it is not essential for termination
B)Transcription will stop immediately because RNA polymerase will sense there is a mutation
C)Transcription will continue until another termination sequence, either Rho dependent or independent is reached
D)There will be no transcription initiation

A mutation in the rut site would affect the efficiency of rho-dependent termination, but it is not the only termination mechanism used by RNA polymerase. Transcription will continue until another termination sequence, either Rho dependent or independent, is reached. Therefore, the correct choice is C.
