mRNAs containing multiple ORFs are known as polycistronic mRNAs, and those encoding a single ORF are known as monocistronic mRNAs.

Prokaryotic mRNAs Have a Ribosome-Binding Site That Recruits the translational Machinery For translation to occur, the ribosome must be recruited to the mRNA.

#Unit 3. Fundamental Processes

Many prokaryotic ORFs contain a short sequence upstream (on the 5’side) of the start codon called the ribosome binding site (RBS). This element is also referred to as a Shine –Dalgarno sequence.

The RBS, typically located 3–9 bp on the 5’side of the start codon, is complementary to a sequence located near the 3’end of one of the ribosomal RNA components, the 16S ribosomal RNA (rRNA).
