Rho-dependent transcription termination requires:
◦ a hairpin structure in the mRNA, the RNA polymerase, and the ρ factor.
◦ a hairpin structure in the mRNA and the RNA polymerase.
◦ a hairpin structure and a
rut site in the mRNA, the RNA polymerase, and the ρ factor.
◦ a
rut site in the mRNA, the RNA polymerase, and the ρ factor.
◦ only the transcribing RNA polymerase and the ρ factor.
