It's maybe a stupid question, but I really want to know the answer.
The definition of Promoter (From Wikipedia):
In genetics, a promoter is a region of DNA that initiates transcription of a particular gene. Promoters are located near the transcription start sites of genes
And the definition of the transcription start site (From Wikiversity):
The transcription start site "is the location where transcription starts at the 5'-end of a gene sequence.
I also Found this image (The source):
I'm asking this question because as far as I know, the RNA Polymerase binds to the TSS, and a friend of mine told me that's it binds to the Promoter.
PS : I'm interested in bacteria.
