Answer:
Explanation:
DNA carries genetic information and keys for the production of every type of cell proteins that control the function of the living organisms.
To reproduce even a single cell, it is necessary to replicate or produce a copy of its DNA.
This is because, after reproduction, all the information of the mother cell has to be passed to the daughter cells, which can only be possible by passing a replicated DNA to the newly born cells.
