Questions and Answers

What determines the specific amino acid to be added to the growing polypeptide chain?

  • The size of the ribosome
  • The 5ʹ-to-3ʹ direction of mRNA translation
  • The complementary base-pairing between the anticodon on tRNA and the next codon on mRNA (correct)
  • The number of tRNA molecules in a cell

In which direction is the mRNA translated?

  • 5ʹ-to-3ʹ direction (correct)
  • Direction is not specified
  • 3ʹ-to-5ʹ direction
  • Random direction

What happens in step 2 of the four-step cycle during protein synthesis?

  • Aminoacyl-tRNA molecule binds to a vacant A site
  • tRNA molecule detaches from the ribosome
  • A new peptide bond is formed (correct)
  • mRNA is translocated
