    Which statement BEST describes the difference between rho-dependent and rho-independent transcription termination in prokaryotes?

    A

    Rho-dependent termination requires a helicase activity, while rho-independent termination relies on a hairpin structure and a poly-U sequence.

    B

    Rho-dependent termination occurs only in the presence of specific antibiotics, while rho-independent termination is the normal mechanism.

    C

    Rho-dependent termination utilizes sigma factor, while rho-independent termination utilizes rho factor.

    D

    Rho-dependent termination involves the formation of a G-quadruplex structure, while rho-independent termination involves a stem-loop structure.
