Answer by realme
eukaryotic cells make up animals, plants, fungi and protists.

these cells have various cell types: skin, eye, nerves, mucles, bones, liver, etc. All these cells started with one fertilized egg which contained the DNA for that individual animal/human.
As the animal embryo grew bigger cells eventually became specialized as these various cell types. That process required duplication of the DNA for cells to be able to divide and contain the same DNA code as the original fertilized egg. During cell division, the DNA came with instructions on which genes were turned off to produce the right kind of cells.

DNA is the code for life and it determines how a given animal or plant will function and grow. So each time a cell divides it needs to duplicate the code for the daughter cells. Mutations happen at times during the cell division, or the DNA is damaged by radiation etc and cancers or other undesirable results happen to the DNA in a cell. Sometimes by accident a mutation can be neutral or beneficial to the animal/plant.

So DNA replication and cell division are the most important functions of living cells on this planet. Without them life as we know it would not exist.
