NGSS.HS-LS3-2

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.

What kind of mutation would have the greatest effect on the protein?

• Missense- 1 amino is changed

• Silent- no amino acids are changed

• Frameshift- all amino acids after the mutation are changed
