Sequences of Rho dependent transcription termination

1. Rho binds a rut site. 

2. The rho factor then tracks along the RNA until it catches up to RNA polymerase. 

3. When the RNA polymerase reaches the termination site, rho first freezes the structure of the polymerase and then invades the exit channel to destabilize the enzyme, causing it to release the RNA. 

4. Pausing by the polymerase at the site of termination allows time for rho factor to translocate to the hybrid stretch.
