What is the role of ribosomes of a polysome?

Show answer & explanation

Correct answer: A

Explanation

The correct answer is Option 1 i.e. Translate the mRNA into proteins

  • A polyribosome is a group of ribosomes bound to an mRNA molecule like beads or thread.
  • It consists of a complex of an mRNA molecule and two or more ribosomes that act to translate the mRNA into proteins, simultaneously from a single mRNA.
  • Ribosomes contain not only amino acids but also ribonucleotide chain in the form of RNA.
  • The genetic code, which is to be translated into protein, is always carried by mRNA.
