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
I am hesitating between 4 options to answer the following question, which option should I choose?
Question: DNA molecules contain the genetic information that determines the characteristics of a living organism. How do DNA molecules express the genetic information they contain?
Possibilities:
- 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
