WebJul 15, 2024 · As DNA replicates during the S phase to prepare the cell for mitosis, each chromatid is copied. Therefore each chromosome is made up of 2 sister chromatids, for a total of 92 chromatids. Humans have 23 different chromosomes (n = 23), for a diploid number of 46 (2n = 46). What does DNA do before mitosis? Before mitosis, DNA … WebDuring S phase, which follows G 1 phase, all of the chromosomes are replicated.
