A2.3 Viruses: grass skirts
19 quick questions on viruses, 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
- 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.- Protein coat enclosing viral nucleic acid
- Host-derived membrane around some viruses
- Virus whose host is a prokaryote
- Infection ending in the host bursting
- Retrovirus that causes AIDS
- Spiked RNA pathogen behind COVID-19
- Complete infective particle outside a host
- Can only reproduce inside a host cell
- Infection in which the host keeps dividing
- Viral DNA spliced into a host chromosome
- Enzyme making DNA from an RNA template
- Respiratory virus with eight RNA segments
- Protein subunit of the viral coat
- Temperate E. coli virus used as a model
- Gradual mutation of surface proteins
- Sudden mixing of genes from two strains
- Idea that viruses are degenerate cells
- Idea that viruses arose from stray genes
- Idea that obligate parasites predate cells
