Multiple Choice

What is the mystery mutation?

• Nonsense

Multiple Choice

A change in a single amino acid due to mutation is known as:

• Missense

• Nonsense

• Frameshift

• Silent

Multiple Choice

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.
