Basal Transcription Apparatus Components

General transcription is required for the growth and survival of all living cells. Scription apparatus resulting in strong transcription of Selected Reading. The general snRNA gene transcription apparatus has been. The latter interact with the basal transcription apparatus and may be modified by phos- phorylation. There are two types of transcription factors that regulate eukaryotic transcription General or basal transcription factors bind to the core promoter region to assist. In negative regulation a repressor protein binds to an operator to prevent a gene from being expressed In positive regulation a transcription factor is required to bind at the promoter in order to enable RNA polymerase to initiate transcription.
