What term describes a group of ribosomes that are translating the same mRNA to produce multiple copies of a specific polypeptide?

The term that describes a group of ribosomes translating the same mRNA to produce multiple copies of a specific polypeptide is polysome. This occurs when several ribosomes attach to a single mRNA molecule simultaneously, allowing for the coordinated assembly of proteins. Each ribosome moves along the mRNA strand, synthesizing a polypeptide chain, which increases the efficiency of protein production. This phenomenon is crucial in cells to rapidly produce large amounts of proteins when needed.

In contrast, the other terms do not apply to this context. Polyspermy refers to the occurrence of multiple sperm fertilizing an egg, which is typically an undesirable event in fertilization. Population generally refers to a group of organisms of the same species living in a particular area, while positive feedback is a biological mechanism that amplifies responses and processes. None of these concepts relate specifically to the simultaneous translation of mRNA by ribosomes, highlighting polysome as the accurate term in this scenario.
