Cells must replicate their DNA before they can divide. This ensures that each daughter cell gets a copy of the genome, and therefore, successful inheritance of genetic traits. DNA replication is an essential process and the basic mechanism is conserved in all organisms.

If a cell hasn't duplicated it's genetic material before it starts dividing, then there will not be enough genetic material to divide...
During the G1 phase the eukaryotic cell cycle is the genetic material duplicated.
The genetic material is duplicated or copied before cell division.

S phase
DNA replication
The genetic material of cells is stored in the nucleolus. It is duplicated by ribosomes in the nucleus.
the S phase
Chromosomes and sister chromatids are joined strands of duplicated genetic material. A chromatid is one copy of a duplicated chromosome which, before replication, is composed of one DNA molecule.
in synthesis (s) phase which is in interphase.
