C3.2.14—Antibiotic resistance evolution Topic Practice
Practise explaining how mutations, plasmids, antibiotic exposure and bacterial reproduction change resistance within populations over time.
How this is tested
- explain how random nucleic acid changes can give bacteria resistance to an antibiotic
- link antibiotic use to survival and reproduction of resistant bacteria in a population
- suggest why colonies may grow despite ampicillin or a repeated antibiotic treatment
