Expression of essential genes is required under all growth conditions but the expression of other genes is conditional. Thus, cells must regulate gene expression using transcription regulation to determine which genes are transcribed and to what extent. Transcription regulation is the most common mechanism to control gene expression in bacteria. Translated By Emaan Chaudry. Adaptation to low oxygen conditions (hypoxia):. Transcriptional Responses.

A eukaryotic transcription initiation complex consists of RNA polymerase II, . five. general transcription factors (GTFs), and a 20-subunit complex called Mediator (or . Srb. /Med). The CTD of RNA polymerase II anchors Mediator to the polymerase. Mediator allows RNA polymerase II to communicate with transcriptional .
