Final answer:
The ribosome-binding site in bacteria is called the Shine-Dalgarno sequence. It interacts with the rRNA molecules in the ribosome and ensures the accurate alignment of the ribosome with the start codon of the mRNA. This site plays a crucial role in protein synthesis.
Step-by-step explanation:
In bacteria, the ribosome-binding site is also called the Shine-Dalgarno sequence. In E. coli mRNA, this sequence interacts with the rRNA molecules that compose the ribosome, anchoring the 30S ribosomal subunit at the correct location on the mRNA template.
The ribosome-binding site ensures the proper alignment of the ribosome with the start codon of the mRNA, allowing for the initiation of translation.
This site plays a crucial role in protein synthesis, as it facilitates the binding of transfer RNA molecules (tRNAs) and the subsequent synthesis of the polypeptide chain.
Overall, the ribosome-binding site is essential for the accurate and efficient translation of mRNA into proteins in bacteria.
