1. The transcription start site (this the base in the DNA across from which the first RNA nucleotide is paired). Sequences that are before the start site are said be upstream sequences. 2. The -10 sequence: this is a 6 bp region centered about 10 bp upstream of the start site.
In eukaryotes, a core promoter sequence in the DNA must be present for RNA polymerase to initiate transcription. Promoters are regions of DNA that promote transcription-in eukaryotes, they are found at -30, -75, and -90 base pairs upstream from the transcription start site (abbreviated to TSS). RNA polymerase creates a transcription bubble, which separates the two strands of the DNA helix. 2  This is done by breaking the hydrogen bonds between complementary DNA nucleotides. 3  RNA polymerase adds matching RNA nucleotides to the complementary nucleotides of one DNA strand.
