how is it possible that in mitosis , after s- phase , the amount of DNA gets double but chromosome number remains the same ?

[Roamer]

Chromosome-number is the amount of DIFFERENT chromosomes.

[CharonY]

Chromosomes consist of two sister chromatids that get separated to the respective cells. Then, the chromatids duplicate in the S phase again.
