A group of ribosomes attached to mRNA is known as:

Correct option is B

The correct answer is (b) Polysomes.

• Polysomes, also known as polyribosomes, are a group of ribosomes bound to a single mRNA molecule simultaneously.
• They enable the simultaneous translation of multiple copies of a protein from one mRNA strand, increasing the efficiency of protein synthesis.
• This arrangement allows for rapid and high-level production of proteins within a cell.
• Each ribosome in a polysome independently synthesizes a polypeptide chain, starting from the same mRNA template.

Information Booster:

Polypeptide:

• A polypeptide is a single linear chain of amino acids, which constitutes the primary structure of a protein.
• It is the product of the translation process carried out by ribosomes.

Polymer:

• A polymer is a large molecule composed of repeating structural units, typically connected by covalent chemical bonds.
• Examples include DNA, proteins, and synthetic materials like plastic.
