cell biology - How is the diploid chromosome number maintained at mitosis?


A normal human cell is diploid that contains 46 chromosomes in 23 pairs. Thus, when the cell undergoes mitosis, the cells still has the full chromosome with the two sister chromatids. What is it doing in interphase when it produces the other chromosomes?


I thought that the sister chromatids were pulled apart and, in interphase, the single sister chromatid grew another one. How is this possible if a human diploid cell contains 23 pairs of 2 chromosomes each?
