  • Give the two types of molecule from which a ribosome is made.
    Ribosomal proteins; ribosomal RNA.
  • Describe the role of a ribosome in the production of a polypeptide. Do not include transcription in your answer.
    1. mRNA binds to ribosome;
    2. Two binding sites;
    3. Allow tRNA with anticodons to bind;
    4. Catalyses the formation of peptide bond between amino acids;
    5. Moves along mRNA to the next codon (translocation).
  • In a eukaryotic cell, the base sequence of the mRNA might be different from the sequence of the pre-mRNA. Explain why.
    The pre-mRNA strand is spliced and introns are removed.
