How Are Polysomes Formed

Polysomes are formed during the elongation phase when ribosomes and elongation factors synthesize the encoded polypeptide. Multiple ribosomes move along the coding region of mRNA, creating a polysome. The ability of multiple ribosomes to function on an mRNA molecule explains the limited abundance of mRNA in the cell.

Where do polysomes occur?

Polysomes are found either free in the cytoplasm or attached to the surface of membranes of the endoplasmic reticulum (ER) and the nucleus.

Where do polyribosomes form in eukaryotes?

On the contrary, in eukaryotes the polyribosomes are formed in the cytoplasm after the completion of the synthesis of mRNA chains and their processing in the nucleus.
