A type of mutation that affect every codon beyond the point of mutation.

• Point Mutation

• Silent Mutation

• Nonsense Mutation

• Frameshift Mutation

TRUE or FALSE. The removal of one base to the DNA sequence might lead to a change on the succeeding (next) codon.

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.
