Two mechanisms of transcription termination and two classes of termination signals have been described in bacteria: rho-dependent and rho-independent (1). The rho-independent termination signals consist of stable hairpins followed by U-rich regions. The mechanism of intrinsic termination includes pausing of the transcription elongation complex.
