What is the role of ribosomes of a polysome?

The ribosomes of a polysome translate the mRNA into proteins.

The correct answer is Option (2) – The ribosomes of a polysome translate the mRNA into proteins.

The role of ribosomes in a polysome is to translate messenger RNA (mRNA) into proteins. Polysomes, also known as polyribosomes, are clusters of ribosomes that simultaneously translate a single mRNA molecule. As the mRNA moves through the polysome, multiple ribosomes attach to it at different sites, each synthesizing a specific portion of the protein encoded by the mRNA. This coordinated action of multiple ribosomes allows for efficient and rapid protein synthesis, contributing to the cell's ability to produce large quantities of proteins needed for various cellular functions. Therefore, the correct statement is:

☀ The ribosomes of a polysome translate the mRNA into proteins.
