1.2 Genes: Answers and Questions
... Mutation – a change in the DNA of an organism; usual order of base pairs is altered which changes genes and effects the proteins produced. Not all mutations are harmful as they can occur in a non-genetic segments of DNA. Mutagen – a substance or factor that can cause a mutation in DNA; DNA is physic ...
