Core promoter, precore and core regions. The core protein was found to be mutated in five of the eight patients in their samples analyzed at baseline and at the onset of the first VBTH ...
(a) Within this simple eukaryotic transcriptional unit, a simple core promoter (TATA), an upstream activator sequence (UAS), and a silencer element are spaced within 100 to 200 base pairs of the ...
In bacteria, promoters are usually composed of three sequence elements, whereas in eukaryotes, there are as many as seven elements. In eukaryotes, the "core" promoter for a gene transcribed by pol ...
