What is a polysome?

A polysome is a complex of multiple ribosomes simultaneously translating a single mRNA molecule. This allows for the rapid and efficient synthesis of multiple copies of a protein from a single mRNA template. Polysomes are commonly found in actively translating cells and are important for protein synthesis.

A polysome is a chain of ribosomes that are attached to a single messenger RNA (mRNA) molecule. Each ribosome is translating the mRNA molecule, synthesizing a polypeptide chain. Polysomes are found in the cytoplasm of eukaryotic cells and are responsible for the production of most proteins.
