DNA molecules contain the genetic information that determines the characteristics of a living organism. How do DNA molecules express the genetic information they contain?

• by breaking down proteins within the cell

• by directing the process of protein synthesis

• by regulating the storage of cellular proteins

• by controlling the movement of protein molecules
