The sigma. () subunit must be present for transcription initiation to occur translation After RNA polymerase moves away from the promotor, it releases the sigma (o) subunit and proceeds with beta (0) beta (8) elongation Termination of transcription may be dependent or independent of the Rho (o) protein factor stability in bacteria, tractation of an ANA transcript can begin while transcription is still taking place polypeptide onhancer Regulation of gene expression can occur during events of transcription, or after transcription Posttranscriptional controls may alter the stability of mRNA, the efficiency of oibosome binding or the stability of the polypeptide product Rho (p)
