KROK 1 2013 – Question 176 · KROK (Medicine) · Biological Chemistry

At the stage of translation in the rough endoplasmic reticulum, the ribosome moves along the mRNA. Amino acids are joined together by peptide bonds in a specific sequence, and thus polypeptide synthesis takes place. The sequence of amino acids in a polypeptide corresponds to the sequence of:

  1. A. rRNA nucleotides
  2. B. rRNA anticodons
  3. C. tRNA anticodons
  4. D. tRNA nucleotides
  5. E. mRNA codons
Hint

Ask which molecule serves as the template that the ribosome actually reads, and how the information in it is arranged to specify each amino acid.
