WebPromoter or cis -regulatory element is a region of DNA at which transcription of particular gene initiates. Generally, promoter consists of three regions—core, proximal, and distal regions. Core region contains transcription start site and binding site for RNA polymerase and it is required for proper initiation of transcription. WebCis-Acting vs Trans-acting elements: There are different elements located around a promoter that are able to modulate gene expression either in a positive or a negative expression manner....
