The chromosomes.
The phase of the cell cycle that duplicates chromosomes before division is called the S phase.
DNA duplicates during the S phase of the cell cycle, which occurs before cell division in the interphase stage.

In simplier form it occurs in the Interphase.
Interphase occurs once for cells undergoing meiosis. During interphase, the cell duplicates its DNA and prepares for division. After interphase, meiosis involves two rounds of cell division (meiosis I and meiosis II), but interphase itself is not repeated between these divisions.
Interphase is the stage in the cell cycle where a cell grows, carries out its normal functions, and prepares for cell division. During interphase, the cell duplicates its DNA and organelles in preparation for cell division. It is the longest phase of the cell cycle.
The process you are describing is known as mitosis, which is a type of cell division that results in two genetically identical daughter cells. During mitosis, the cell's nucleus, along with its chromosomes, duplicates and then divides into two separate nuclei. This is followed by cytokinesis, where the cell's cytoplasm divides, completing the formation of two new cells. Mitosis is essential for growth, repair, and asexual reproduction in organisms.
During interphase, a cell grows in size, duplicates its organelles, and carries out normal cellular functions such as protein synthesis and energy production. This phase is important for preparing the cell for division.
Cell division begins with a single parent cell that duplicates its genetic material and then divides into two daughter cells. This process ensures that each new cell receives a complete set of genetic information from the parent cell.
Interphase has three phases: G1--The cell is functioning normally but preparing for cell division so it makes more proteins, organelles and increases the volume of cytoplasm. S-"Synthesis"--The cell duplicates its DNA. G2--The cell continues growing to prepare for cell division.
