Question 19

What is the function of a polysome? (Gk. Poly = many, Soma = body)

A polysome consist of a cluster of ribosomes that are held, simultaneously by a strand of messenger RNA (mRNA) in rosette or helical group.They contain a portion of the genetic code that each ribosome is translating and are used in formation of multiple copies of same polypeptide. They are found in the cytoplasm during the process of active protein synthesis.
