  1. 3. The shape of a tRNA molecule. (two words)
  2. 4. Small subunit attaches to the mRNA here. (HL) (three words)
  3. 6. A type of nucleic acid that carries the sequence information of a single gene.
  4. 7. The distance moved by the ribosome along mRNA during translation. (two words)
  5. 9. This means that some amino acids have more than one codon.
  6. 14. This nucleic acid is part of the structure if the ribosome.
  7. 16. These structures are found in prokaryotic cells because cytoplasm has no compartments and therefore several translation can start before transcription is completed. (HL)
  8. 17. The sequence and number of amino acids in a polypeptide gives it a …(two words)
  9. 20. A type of nucleic acid that is charged with an amino acid.
  10. 22. There are three of them that indicates the end. (two words)
  11. 25. When to start translation.
  12. 26. Proteins like hemoglobin, collagen and antibodies are said to have these types of structures.(HL)
  13. 27. The synthesis of polypeptides using a nucleic acid template.
  14. 28. They can be free or attached in the cytoplasm.
  15. 30. Where translation occurs in prokaryotes. (Phrase)
  16. 31. This means that codons are read in the same way by all organisms.
Down
  1. 1. The direction the ribosome’s moves along the mRNA molecules during translation. (Phrase)
  2. 2. Where peptide bonds are formed between two adjacent amino acids. (two words)
  3. 5. enzyme Catalyzes the binding of amino acid to the tRNA molecule. (HL)
  4. 8. The folding of the polypeptide due to intramolecular hydrogen bonds gives a polypeptide its …… (two words)
  5. 10. Where the mRNA binds (two words).
  6. 11. here. (two words)
  7. 12. Proteins destined to be used in the cytoplasm of the cell are synthesised here. (two words)
  8. 13. Usually the first amino acid as it shares the same codon as start.
  9. 15. Proteins that are destined for use in the ER, the
  10. 18. The part translated first in a polypeptide that is to be excreted from the cell. (HL) (two words)
  11. 19. The tertiary structure of a polypeptide arise from the interaction of these groups within the chain. (Phrase)
  12. 21. Found on one loop of the tRNA and necessary to form hydrogen bonds with mRNA.
  13. 23. apparatus, lysosomes, the plasma membrane or outside the cell are
  14. 24. The terminal end which binds the amino acid on tRNA. (HL)
  15. 27. How many tRNA molecules can be bound to the Ribosome at any one time?
  16. 29. There are 64 of them recognized by all living organisms.
