  • WHAT HAPPENS IN TRANSLATION?
    polypeptide chain created using mRNA base sequence and tRNA
  • PROCESS OF TRANSLATION?
    1. mRNA attaches to ribosome in cytoplasm
    2. Ribosome attaches at start codon
    3. tRNA molecule with complementary anticodon (to start codon) aligns opposite the mRNA
    4. Held in place by ribosome
    5. Ribosome will move along one codon on mRNA molecule
    6. Enables another complementary tRNA to attach to next codon on mRNA
    7. Two AAs from tRNA joined by peptide bond (requires ATP, enzyme catalyses)
    8. Continues until ribosome reaches stop codon on end of mRNA (does not code for AA)
    9. Ribosome detaches
    10. Translation ends
    11. Polypeptide chain created
    12. Enters Golgi Body for folding/ modification
