The Shine-Dalgarno sequence found in prokaryotic systems resides on the 5'-end of mRNA.What function does the site serve?

Question

Quizplus · Accepted Answer

The Shine-Dalgarno sequence is responsible for ribosome binding on the mRNA in prokaryotic systems. It is approximately 6-8 nucleotides long and located on the 5'-end of the mRNA, upstream of the start codon. The complementary sequence to the Shine-Dalgarno sequence is located on the 3'-end of the 16S rRNA of the ribosome. The binding of the ribosome to the mRNA at this site is necessary for translation initiation.
