Why does rho- dependent transcriptional termination in bacteria require the rho protein?
A) The rho protein assists in formation of the termination stem- loop that pauses the RNA Polymerase.
B) RNA Polymerase stalls at various sites in the gene and rho helps push RNA Polymerase to the end of the gene.
C) The rho protein helps unwind the stem- loop structure after the RNA has been released by RNA Polymerase.
D) The stem- loop is insufficiently stable to displace the RNA Polymerase by itself and needs rho protein to assist.
E) RNA Polymerase stalls on the termination stem- loop and rho is needed to displace the RNA Polymerase.

The rho protein is required for rho-dependent transcriptional termination because it actively displaces the RNA Polymerase that stalls on the termination stem-loop, allowing the transcription to terminate properly.
