Rho factor
$Rhofactor$

The Rho factor is a specific chain terminating protein which binds to the RNA polymerase at times to facilitate the termination of transcription.

It recognises a specific sequence on the template strand and causes the RNA Polymerase to leave the template strand and release the RNA transcript completely.
