DNA and RNA EOC review

When do genetic mutations get passed from parent to offspring?

• When the Gametes (sex cells) are mutated

• When the mutation changes the order of DNA

• When the mutation occurs randomly

Mutations can be...

• Harmful

• Beneficial

• Neutral

• All of the Above

Your enzymes can repair some mutations

• True

• False

Mutations are...

• Changes in the sequence of DNA

• Broken chromosomes

• Bad genes

Body Cell mutations can contribute to...

• Cancer

• Parkinson's Disease

• Bronchitis

• Heart Failure

Mutations can be a result of...

• Environmental Exposure

• Lack of sleep

• Not enough exercise

What is a type of Mutation?

• Deletions

• Insertions

• Base Substitutions

• All of the Above

Why do most changes to DNA have NO effect at all?

• Because they're too minor to have any effect

• Because the changes are offset by RNA, which cannot change

• Because the changes are quickly repaired

• Because the changes only occur in a few cells
