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 termination 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
