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 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 is the building block of DNA

• Monosaccharide

• Amino Acid

• Fatty Acid

• Nucleotide

Mutations can benefit humans because they can:

• Cause illness

• Make an organism more suited to live in its environment.

• Make organisms live shorter lives

• Cause organisms to grow extra limbs.

Mutations can be negative because

• They can cause cancer

• They can cause birth defects

• They can help an organism thrive in its environment.

• They can affect offspring.
