NGSS.HS-LS4-2

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.

Why is the order of amino acids so important?

• The order of amino acids dictates what shape the protein will fold into.
• It is not important. The protein folding chamber will force the protein to fold into the correct shape.
