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

Set out your lesson
“If your child 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?”
Full guide and materials
- Activity. 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
What to notice. 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
