Translate the mRNA into proteins |
The correct answer is Option (1) -Translate the mRNA into proteins The correct answer is: ☀ Translate the mRNA into proteins Polysomes, also known as polyribosomes, are clusters of ribosomes that are bound to a single mRNA (messenger RNA) molecule during protein synthesis. The primary role of ribosomes in a polysome is to translate the genetic information carried by mRNA into proteins. The process involves reading the sequence of nucleotides on the mRNA and using that information to synthesize a corresponding polypeptide chain, which eventually folds into a functional protein. Ribosomes are composed of both protein and ribosomal RNA (rRNA), and they facilitate the assembly of amino acids into a growing polypeptide chain according to the instructions encoded in the mRNA. Polysomes allow for simultaneous translation of multiple ribosomes along the same mRNA molecule, increasing the efficiency of protein synthesis. This coordinated effort is crucial for the production of proteins, which play various roles in cellular functions and organismal processes. |
