Mutations

Definition

• A mutation is a change in an organism’s DNA– Silent mutations are changes that do not

result in a change to the organisms phenotype

–Mutations that occur in germ cells (sperm, eggs) are passed on to offspring

–Mutations in somatic (body) cells may be harmless, or may result in disease such as cancer

Chromosomal Mutations

A Point Mutation Resulting in Nonsense

Page 5: Mutations. Definition mutation A mutation is a change in an organism’s DNA – Silent mutations are changes that do not result in a change to the organisms

A Point Mutation: An Analogy

An Insertion Mutation in a Gene

Page 9: Mutations. Definition mutation A mutation is a change in an organism’s DNA – Silent mutations are changes that do not result in a change to the organisms

An Insertion Mutation: An Analogy
