DNA: agent or bridge?

Who is really in charge—DNA or the cell? The “library” of chromosomes, or the vast coordinated ecosystem inside the cell? Well, if DNA is really just a set of instructions, then how can we call it the agent and end of all the various episodes of biological struggle?

Or is it just the temporal bridge between what really matters—sequential incarnations of the struggling (and sentient) cell? It is not a miniature of the cell, but a flattened and stripped version, incapable of life but more capable of resisting entropy. Take a seed or a mushroom spore. These are practically immortal, but they are not alive like trees and mycelia.
