Question

DNA contains genes which are the units of heredity and carry the information for the development and functioning of organisms. Gametes are cells involved in sexual reproduction, proteins have various functions but do not directly control inheritance, and temperature is an environmental factor with no direct role in controlling traits and inheritance.
