DNA structure and replication: grass skirts
12 quick questions on AP Biology topics 6.1 DNA and RNA Structure and 6.2 DNA Replication, 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
- SnipA runner cuts one strip off the bottom of their team’s sheet.
- Answer as a pairBack at the table, they write the answer on the strip. No books.
- Get it checkedThe checker reads it against the key: you, or a student holding it.
- 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.- Small DNA ring apart from the chromosome
- Enzyme that unzips DNA at the fork
- Enzyme building new strands from a primer
- Protein that DNA winds around
- Each new helix keeps one old strand
- Enzyme making RNA starters for replication
- Enzyme that seals nicks between fragments
- Copy built continuously toward the fork
- Copy built discontinuously
- Short DNA pieces later joined by ligase
- Enzyme making DNA from an RNA template
- Relieves supercoiling ahead of the fork
