Protein synthesis — practice question

Electron micrographs can reveal many ribosomes arranged in chains along mRNA molecules. What advantage does this arrangement have, compared with ribosomes being present singly on the mRNA?

  • BFewer tRNA molecules are required to translate the polypeptide.
  • CLarge polypeptide chains can be produced.
  • DPolypeptides can be produced more rapidly.
