Mutations Practice

Gene: ∎∎⊙∎∎

Mutation: ∎⊙∎∎∎

What mutation occurred?

• deletion

• duplication

• inversion

• translocation

A type of substitution in which no amino acids change is called

• Missense

• Nonsense

• Silent

• Deletion

original chromosome

ABCDEF

mutated chromosome

ACDEF

This is a _____________ mutation.

• transposon

• inversion

• deletion

• translocation

Mutations are only passed on to offspring when they happen in

• somatic cells

• gamete cells

• prokaryotic cells

• the mitochondria

Would a mutation in the DNA of a skin cell be passed on to an organism's offspring?

• Yes, because any change to the DNA is passed on to the offspring
• Maybe. Sex cells only use half of the body's genetic code. It might get the copy of a gene that wasn't mutated.
• No. Only mutations that occur in the gametes (sex cells) are passed on to the offspring
• Without knowing the animal, it would be hard to tell whether or not the mutation would be passed on.
