The correct answer is that it directs cellular activity.
DNA undergoes transcription to produce mRNA, which then translated into proteins. Proteins plays a variety of roles in the cellular activities. For example protein can serve for structural support, they can exist in the form of enzymes that catalyze reactions, and functions as messengers.
