Deoxyribonucleic Acid (DNA)
Mitosis
It is important for chromosomes to make copies of themselves before mitosis to ensure that each daughter cell receives a complete set of genetic information. The copied chromosomes, known as sister chromatids, are then separated during mitosis to ensure equal distribution of genetic material to the two daughter cells. This process helps maintain genetic stability and prevents loss of important genetic information.
Just before cell division begins,the amount of DNA doubles and so do the chromosomes.Each doubled chromosome consists of two copies of the original chromosome joined at the center
When bone cells divide they must produce cells exact copies of themselves.
DNA replication occurs during the S phase of interphase, which is the phase that precedes mitosis. In this phase, the DNA molecules in the cell's nucleus are duplicated, resulting in two identical copies of each chromosome.
Mitosis
Before mitosis begins, a cell has a diploid number of chromosomes, which means there are two sets of chromosomes. This is because during interphase, before mitosis begins, the DNA has already replicated, so the cell contains identical copies of each chromosome.
The chromosomes are copied, so that each daughter cell has an exact copy of the genetic material.

DNA copies itself during the S phase of the cell cycle, which occurs before mitosis.
The process of cell division is called mitosis. Without division, you and I wouldn't grow as we do.
Before mitosis begins, the chromosomes in a cell replicate. This occurs during the S (synthesis) phase. Chromosomes need to replicate so that when the cell divides at the end of mitosis, the daughter cells each recieve a copy of the chromosomes.
