After DNA replication, there are double the number of chromosomes, which will be divided into two identical daughter nuclei during mitosis. For example, a normal human body cell has 46 chromosomes. When it undergoes DNA replication, the chromosomes are doubled so that there will be 92 chromosomes, consisting of 46 pairs of sister chromatids. During mitosis, the sister chromatids separate into two identical daughter nuclei, each having 46 chromosomes.
