Unit 6, Gene Expression and Regulation: grass skirts

53 quick questions across the whole of Unit 6 (a fresh 30 on each print), 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 DNA winds around
  2. Small DNA ring apart from the chromosome
  3. Each new helix keeps one old strand
  4. Enzyme that unzips DNA at the fork
  5. Relieves supercoiling ahead of the fork
  6. Enzyme making RNA starters for replication
  7. Enzyme building new strands from a primer
  8. Enzyme that seals nicks between fragments
  9. Copy built continuously toward the fork
  10. Copy built discontinuously
  11. Short DNA pieces later joined by ligase
