it ensure that the cell can survive before it gets divided
the parts of the cell which are copied during cell division are chromosomes.
To make all cells identical.
Chromosomes are copied when the Anaphase is there.
Interphase before Prophase I.
The consist of DNA and various HistonesIn eukaryotes,genetic information is passed on by chromosomes. Well before cell division, each chromosome is replicated(copied). When copying occurs, each chromosome consists of two identical ''sister''chromatids.
DNA is copied
DNA must be copied before cell division so that one complete copy of each chromosome ends up in each of the two daughter cells. Otherwise only one cell would end up with DNA, making the other cell.. well.. not a cell.
It ensures that each newcell will be an exactcopy of its parent cell.
I think that because you when you copy something you are making an exact replica of it.

Chromosomes are copied during S phase, before cell division begins. This is so that each daughter cell receives the right amount of genetic material. In mitosis, the daughter cells receive the same number of chromosomes as in the original cell, in meiosis they receive half of this.
They are copies because so that new cells have the same chromosomes as their parent cells.Because each daughter cell needs its own set.
