Promoter region

In prokaryotes, two important areas in the promoter
region are 35 and 10 nucleotide base
pairs upstream of (in the 5! direction) the
starting point of transcription. Mutations in the
region of the regulative sequences (promoter
region) in certain regions are extremely sensitive
to base substitution (mutation), an indication
of their importance.
