Any change in the sequence of DNA is...

• transgenic shift
• Single Genotype
• Monohybrid Trait
• 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.
