RNA polymerase stops transcribing DNA into RNA at terminator sequences. Rho dependent termation is one of the two types of termination. Rho factor is a helicase, composed of six identical subunits, that unwinds RNA-DNA and RNA-RNA duplexes. This unwinding is powered by the hydrolysis of nucleoside triphosphates.
