During which stage does dna replicate

WebMitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. Some textbooks list five, breaking prophase into an early phase (called prophase) and a late phase (called prometaphase). These phases occur in strict sequential order, and cytokinesis - the process of dividing the cell contents to make two new cells - starts ... WebJul 17, 2024 · There are two stages or phases of meiosis: meiosis I and meiosis II. Before a dividing cell enters meiosis, it undergoes a period of growth called interphase. At the end of the meiotic process, four daughter cells are produced. G1 phase: The period prior to the synthesis of DNA.
