Genetic Mutation
Explain genetic mutation as a random change in DNA sequence, describe causes of mutation (e.g. radiation, chemicals, copying errors), and explain that most mutations are neutral, some harmful, and a few beneficial
Suggested ages 12–14
Evidence of understanding
- Defines mutation as a change to DNA sequence
- Names at least two things that can cause mutations (mutagens)
- Explains that mutations are the original source of all genetic variation
- Explains that beneficial mutations can be selected for by natural selection
Assessment prompt
If Genetic Mutation heard that DNA can get damaged or changed, could they explain what a mutation is, what might cause one, and why most mutations don’t actually cause problems — but occasionally one leads to something new?
