Promoter sequences are DNA sequences that define where transcription of a gene by RNA polymerase begins. Promoter sequences are typically located directly upstream or at the 5' end of the ...

This polymerase contains four catalytic ... sequences in the DNA), these elements constitute the core promoter. However, changes in RNA pol II affinity and, therefore, gene expression can be ...

These proteins impart on RNA polymerase the ability both to recognize promoter DNA, and to orchestrate the strand separation that accompanies formation of a transcription-competent RNA ...

This process is carried out by the enzyme RNA polymerase, which binds to specific promoter regions on the DNA and initiates the synthesis of the complementary RNA strand. The resulting primary ...
