NGSS.HS-LS3-2

Mutated DNA sequences that can be passed from parent to offspring --

• occur in somatic cells (body cells)
• occur in gametic cells (sex cells)
• are rejected by meiosis
• only occur if the parent is exposed to harmful substances

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.
