Mutation

Muscle cells differ from nerve cells mainly because they

• express different genes.

• contain different genes.

• use different genetic codes.

• have unique ribosomes

Why is DNA important?

• it is very small and very complicated
• it's in everything
• it serves as the blueprint for traits of all living things
• because we eat it every day for energy
