D2.2 Gene expression: grass skirts

15 quick questions on gene expression, a higher level subtopic, 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. Making a functional product from DNA
  2. Full set of DNA a cell carries
  3. Protein that binds DNA to regulate genes
  4. Distant DNA site that boosts transcription
  5. DNA site just upstream of a gene
  6. All the mRNA being made in a cell
  7. All the polypeptides a cell produces
  8. Adding CH₃ groups to cytosine bases
  9. Mark that alters gene activity, not code
  10. DNA wound round eight histones
  11. Cross of a male lion and a female tiger
  12. Cross of a male tiger and a female lion
  13. Siblings from one fertilized egg
  14. E. coli genes induced by a milk sugar
  15. Passing on activity patterns, not sequence
