D1.3.5—Randomness in mutation Topic Practice
D1.3.5—Randomness in mutation Topic Practice
Practise recognising that mutations occur randomly while their frequency can still be affected by external factors such as mutagens.
How this is tested
- distinguish random occurrence of mutations from changes in mutation frequency
- apply MCQ evidence to reject claims that mutations happen only in germ cells
- explain why random mutation does not mean mutation rate is fixed
