Which of the following would result in a frameshift mutation?

• Insertions only
• Substitution only
• Deletion only

• Deletion Mutation

• Point Mutation

• Insertion Mutation

Why are insertion and deletion (frameshift) 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.
