(3 days ago) Promoter is always located near to the transcriptional unit of the gene. Promoter contains special DNA sequences that ensure the specific binding of RNA polymerase at the correct binding site for the correct transcription of the transcriptional unit. Main elements of the promoter region are core promoter element and regulatory elements.

Promoter (genetics) - Wikipedia

(1 months ago) In genetics, a promoter is a region of DNA that leads to initiation of transcription of a particular gene.Promoters are located near the transcription start sites of genes, upstream on the DNA (towards the 5' region of the sense strand).Promoters can be about 100–1000 base pairs long.

Regulation of Gene Expression via the Core Promoter and ...

(3 years ago) Role of the Core Promoter in the Regulation of Gene Expression. Transcriptional regulation is achieved not only by diversity in enhancers, but also by diversity in core promoter structure (see, for example: Smale, 2001; Butler and Kadonaga, 2002). This effect is seen, in particular, in the area of enhancer-promoter communication.
