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

A Point Mutation: An Analogy

t h e r e d d o g b i t t h e t a n c a t

t h e r e d m o g b i t t h e t a n c a t

This point mutation changes the meaning, resulting in nonsense

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

t h e r e d d o g b i t t h e t a n c a t

t h e r e d r d o g b i t t h e t a n c a

This insertion mutation changes the reading frame

A Deletion Mutation in a Gene

Page 11: 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 Deletion Mutation: An Analogy
