WebDec 17, 2016 · The first division of meiosis, meiosis I starts after a cell goes through interphase. As in the case of interphase preceding mitosis, each chromosome is replicated during synthesis of interphase. Thus, when meiosis starts, there are two copies of each chromosome, attached as sister chromatids in the same chromosome. WebHowever, interphase does not describe a cell that is merely resting; rather, the cell is living and preparing for later cell division, so the name was changed. A common misconception is that interphase is the first stage of mitosis, but since mitosis is the division of the nucleus, prophase is actually the first stage.
