How does the structure of DNA result in functional differences in cells?

• Different DNA bases means different amino acids. Different amino acids means different proteins. Different proteins means different things for cells to do.

• Structural differences in DNA does not impact what cells do.

• Structural differences in DNA only occur if there is a mutation. Mutations are always bad.
