D1.2 Protein synthesis: grass skirts

22 quick questions on protein synthesis, 15 of them at standard level, each answered in a word or two. Print a sheet for each team, a key for the checker and a tick sheet, then tape the sheets to the board and race.

How it runs

  1. SnipA runner cuts one strip off the bottom of their team’s sheet.
  2. Answer as a pairBack at the table, they write the answer on the strip. No books.
  3. Get it checkedThe checker reads it against the key: you, or a student holding it.
  4. Back for the nextA tick earns the next strip. Wrong? Back to the table to try again.

The questions on this sheet

The checker’s key, with every answer, prints with the sheets.
  1. Copying a gene's base sequence into RNA
  2. Enzyme that builds mRNA along a gene
  3. Carries a gene's code to a ribosome
  4. rRNA and protein structure that reads mRNA
  5. Carries an amino acid to the ribosome
  6. Making a polypeptide from an mRNA code
  7. mRNA triplet specifying an amino acid
  8. Three tRNA bases that pair with mRNA
  9. DNA chain that mRNA is complementary to
  10. DNA chain with the same sequence as mRNA
  11. First triplet read on an mRNA
  12. Triplet that ends a polypeptide chain
  13. Most amino acids have more than one codon
  14. Same codons mean the same in all organisms
  15. Glutamic acid to valine in haemoglobin
  16. DNA sequence where RNA polymerase binds
  17. Non-coding section cut out of pre-mRNA
  18. Coding section kept in mature mRNA
  19. How one gene can give several proteins
  20. Complex that degrades tagged polypeptides
  21. Amino acid carried by the initiator tRNA
  22. Adenine nucleotides added at the 3′ end
