The chromosomes are copied, so that each daughter cell has an exact copy of the genetic material.
The DNA makes copies of its self.
Mitosis
DNA replication results in two identical copies of each chromosome. There needs to be two copies of each chromosome so that at the end of mitosis each daughter cell has the exact same number and types of chromosomes as the original cell. In other words, the daughter cells must have the exact same DNA as the original cell so that each cell has the instructions for carrying out cellular functions.
Cell Division: A cell must go through Interphase, where the cell prepares for division, and makes a copy of its DNA. It then goes on to Mitosis, which has 4 stages (prophase, metaphase, anaphase, and telophase) during which stages it basically sends on its copies of DNA (chromosomes) to the daughter cells. Then it goes on to Cytokinesis where the cell finishes splitting into two daughter cells, and the chromosomes are equal to the parent cells before Cell Division...
Before meiosis begins, the cell copies its DNA in the process of DNA replication.
Mitosis
When the cell prepares for mitosis, takes inventory and makes sure it is ready to continue with mitosis

Samsung makes these registers that can print copies of receipts.
Chromosomes duplicate in a process called mitosis.
Before the nuclear envelope of a cell breaks down during the mitosis process, the DNA has to be duplicated. After the envelope dissolves, the chromosomes separate, then the cell finally splits.
Yes, organelles such as mitochondria and chloroplasts replicate themselves before cell division through a process called division, ensuring that each daughter cell receives the necessary organelles for its functions. Other organelles like the Golgi apparatus and lysosomes are mostly recycled and rebuilt after cell division.
