DNA by itself doesn't produce a human or a cell. You need another functional cell or human to create a replica. I would compare DNA with instructions to create a new car: the instructions are incomplete and assume the existence of a car factory. DNA tells "now paint the car with of these colors", but it doesn't tell how.

Computer programs don’t include the CPU design. DNA on the other hand encodes everything which then gets leveraged during cell division.

Basically, DNA includes the design for both the car, car factory, and all the component factories that feed the car factory, and the mines that feed the component factories. People have dependencies on their diet for things like vitamin C, but that’s a whole other issue.

PS: Mitochondria also have DNA, but that’s just location specific and can simply be added to the total for the cell.

Why do you think DNA includes everything?

Mitosis and RNA.
