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.
