The chromosomes line up in the middle at the metaphase plate, and the sister chromatids are attached to the kinetochore microtubules coming from opposite poles.Īnaphase comes next, which is when the spindle fibers begin to shorten and the two sister chromatids of each pair start to part, moving toward opposite ends of the cells. Next, during metaphase, the nuclear envelope completely dissolves and the centrosomes are now at opposite polls of the cells. The nucleoli disappear during this phase and the mitotic spindle begins to form. The cetrosomes have duplicated, and chromosomes cannot be seen yet. Interphase takes part during the G2 cycle. The cell spends most of cell life in Interphase, however, which is a time for cell growth and DNA replication. Mitosis can be broken down into five major phases: Prophase, Prometaphase, Metaphase, Anaphase, and Telophase. Introduction: Mitosis is the process in which a cell divides, splitting the nucleus, and creating two identical daughter cells. However we did our best, and we are both really happy with the outcome of our project! Reece, Jane B. Both Abi and I were originally unclear about the general process of meiosis, and we found that this confusion on top of the struggle of using Pipe Cleaners and the time crunch resulted in a lot of difficulties. Meiosis is similar to mitosis in that the cell goes through similar phases in both processes.
Meiosis is a form of sexual reproduction and cell division.
