Types of Mutation

What are the types of Point/Substitution Mutations?

• Insertion, Deletion, Frameshift

• Insertion, Deletion, Point

• Missense, Nonsense, Deletion

• Missense, Nonsense, Silent

When a nucleotide is changed, but the amino acid stays the same, this is a _____________ mutation.

• silent

• missense

• nonsense

• start-stop

A start-stop mutation is called a ________ mutation.

• insertion

• deletion

• silent

• nonsense

True or False: A mutation is permanent?

• True

• False

Frameshift mutations are

• insertion and deletion

• insertion and silent

• insertion and missense

• insertion, deletion, and missense

Which mutation would you most likely prefer?

• missense

• silent

• nonsense

• frameshift

What type of mutation adds to the strand?

• missense

• nonsense

• insertion

• deletion

Looking at both mutations, why are these mutations harmful.

• They are not harmful.

• They both add to the strand.

• They both delete the strand.

• They change the amino acid sequence.

When a silent mutation happens, ___________.

• the amino acid changes

• the amino acid does not change

• the amino acid is deleted

• another nucleotide is added
