DNA Structure and Replication
The higher order structure of DNA shows symmetry, whereas the higher order structures of most proteins do not. Why isn't protein shape more regular like DNA?

All of these
Some S amino acids cause proteins to bend; others cause protein to flatten.
DNA has one main function in cells whereas proteins have many.
The many different amino acid R groups on proteins confer many different shapes.
