Regulating gene expression: grass skirts

13 quick questions on AP Biology topics 6.5 Regulation of Gene Expression and 6.6 Gene Expression and Cell Specialization, 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. Protein that blocks the operator
  2. Protein that helps RNA polymerase bind
  3. Becoming a specialized type, e.g. neuron
  4. Unspecialized, able to become many types
  5. Inducible genes for digesting milk sugar
  6. Repressible genes for making an amino acid
  7. DNA switch where a repressor binds
  8. Molecule that inactivates a repressor
  9. Distant DNA site that boosts expression
  10. Tagging cytosines to silence genes
  11. Loosens chromatin to turn genes on
  12. Master switches for the animal body plan
  13. Silencing of an mRNA by small RNAs
