A cell makes copies of its DNA before it divides to pass on it's genetic information to the new cell. The parent cell needs to keep a DNA copy for itself to continue to replicate and adapt. That's right, all is not set in stone. Research shows DNA is adaptive, too. It responds to the environment, available food supplies, etc.
Because each cell needs its own set of DNA, there must be two sets of DNA present in a cell before it divides into two.
Before a cell divides, it must replicate its DNA to make an exact copy of all its genetic material. This ensures that each daughter cell receives a complete set of genetic instructions necessary for proper functioning. The process of DNA replication is crucial for maintaining the genetic integrity of the cell and passing accurate genetic information to the next generation.
So that the new cells have the same chromosomes as the parent cells.
the cell divides in two (and again and again), every 20 minuets in good conditions. The cell wont be an exact copy because before it divides it copies the DNA but sometimes it dosent match up and a the new cell will be mutated

It must make a copy of its deoxyribonucleic acid (DNA).

It. Divides
as cell divides the DNA also hav to divide to b transfferd in to newly formed cell so for that DNA divides
When a parent cell makes several nuclei and divides to make several daughter cells, it is called multiple fission. This process is common in some protists like amoebas and algae where multiple nuclei are produced before the cytoplasm divides to form several daughter cells.
