Summary Introduction

To explain:

The differences and similarities between the RNA polymerase II and rho-independent termination.

Introduction:

There are three RNA polymerases found in all eukaryotes and all use different mechanism of termination. Transcription process by RNA polymerase II is terminated when an exonuclease enzyme binds to the cleaved $5\text{'}$ end of the RNA. Rho-factor is a prokaryotic protein which is involved in the termination of transcription process when the RNA forms a hairpin loop structure which displaces RNA polymerase and stops transcription process.
