Mutation - GCSE Physics Definition

In GCSE Physics, a mutation is a change that occurs in the DNA sequence of an organism's genes. DNA is like a set of instructions that tells cells how to build and maintain the body. Sometimes, changes happen in the DNA, and these are called mutations. They can occur naturally when cells divide or be caused by external factors like radiation. Mutations can have different effects: some may have no impact at all, while others might lead to changes in an organism's characteristics and cause illnesses such as cancer. Although mutations are more commonly discussed in biology, understanding them helps in physics when studying the effects of radiation on living things.
