NGSS.HS-LS1-1

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

Tags

NGSS.HS-LS3-2

a change in one DNA triplet that may result in a new triplet that codes for a stop codon instead of an amino acid is known as

• missense
• nonsense
• frameshift
• silent

NGSS.HS-LS3-2

Nonsense mutations result in ____________________.

• a stop codon

• the same amino acid as the original

• a different amino acid than the original
