A Shine- Dalgarno sequence- a short (4- 9 nt) sequence about 7 nt before (5' to) the AUG which are complementary to the 3' end of the 16s rRNA. It is the pairing between the 16s rRNA and the mRNA at the Shine- Dalgarno sequence that determines which AUG triplet will start the reading frames of the message.
