Mutations

Any change in the sequence of DNA is...

• transgenic shift
• Single Genotype
• Monohybrid Trait
• Mutation

Mutated DNA sequences that cannot be passed from parent to offspring --

• occur in somatic cells (body cells)

• occur in gametic cells (sex cells)

• are rejected by meiosis

• only occur if the parent is exposed to harmful substances

Are all mutations bad?

• Yes
• No
• Maybe?

Mutations can benefit humans because they can:

• Cause illness

• Make an organism more suited to live in its environment.

• Make organisms live shorter lives

• Cause organisms to grow extra limbs.

True or false, mutations create genetic diversity?

• True

• False

All cells in the body except the reproductive cells (gametes, germ, sex cells) are called...

• prokaryote

• eukaryote

• somatic cells

• sperm and egg

Reproductive cells –sperm/egg in humans are called

• prokaryote

• eukaryote

• somatic

• gametes

Which of the following would result in a frameshift mutation?

• Insertions only
• Substitution only
• Deletion only
• Insertions and Deletions

Why are insertion and deletion mutations so harmful?

• They change all of the codons from the mutation on down the line, which changes the amino acid sequence

• They insert things that an organism doesn't need.

• They often delete things that organisms need.

• Insertion and deletions are not any more harmful than substitution mutations.
