The expression of genes into proteins and is a process involving two stages called transcription and translation. In the transcription stage a strand of DNA molecule serves as a template for the synthesis of an RNA molecule called messenger RNA. This messenger RNA is then translated into proteins on ribosomes. The transcription step that involves the synthesis of mRNA from can explained in the following stages. | The expression of genes into proteins and is a process involving two stages called [[transcription]] and [[translation]].

Specific DNA sequences rich in T followed by G-C rich sequences are responsible for termination of transcription. When RNA polymerase reaches these T rich sequences it pauses and the synthesized RNA is released. The termination process is aided by a protein called rho factor. It binds to RNA polymerase, RNA and DNA at the pause signal and RNA is released. | Specific DNA sequences rich in T followed by G-C rich sequences are responsible for termination of transcription.
