Before a dividing cell enters meiosis, it undergoes a period of growth called interphase. At the end of … WebMeiosis is similar to mitosis and must have the cell's DNA replicate before it can begin. This creates chromosomes that are made up of two sister chromatids connected by a centromere. Unlike mitosis, meiosis requires two rounds of division to get half the number of chromosomes into all of the daughter cells.
