After Mitosis, the result is 2 new, identical, daughter cells. In order for each to be identical, the chromosomes must be copied.
Chromosomes duplicate during the S phase of interphase, which occurs before mitosis. Each chromosome replicates to form two identical sister chromatids that are held together at the centromere. These sister chromatids are then separated and pulled to opposite poles of the cell during mitosis.
Just before mitosis, a chromosome consists of two sister chromatids joined by a centromere. Each sister chromatid contains one DNA molecule. Therefore, there are two DNA molecules in a chromosome just before mitosis.
DNA is replicated during the Synthesis (S) phase of cell growth. This comes after G1 and before G2. Mitosis follows G2.
Mitosis
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
Chromosomes are copied in the form of sister chromatids during S-phase of the cell cycle, which are then separated during mitosis. The centrioles also duplicate before mitosis begins to ensure proper formation of the mitotic spindle and accurate segregation of chromosomes.

DNA is copied in the S-Phase of cellular division through a process known as mitosis. It does so by duplicating each chromosome in anticiaption of cell division.
DNA is not copied during mitosis . Mitosis is meant for division of cell and DNA is divided in two daughter cells .
Just before mitosis, a chromosome consists of two sister chromatids joined by a centromere. Each sister chromatid contains one DNA molecule. Therefore, there are two DNA molecules in a chromosome just before mitosis.
Chromosomes are duplicated before mitisis in S phase of inter phase .
it is called a sister chromosome :)

DNA is replicated during the Synthesis (S) phase of cell growth. This comes after G1 and before G2. Mitosis follows G2.
Two chromatids are present in a chromosome at the beginning of mitosis.
During mitosis, the chromosome number remains the same. The cell duplicates its chromosomes before dividing, so each daughter cell receives the same number of chromosomes as the parent cell.
