Mitosis :|

Hmmm....Mitosis is another type of cell division based from what I learned from the lessons. It seperates the cell into two and each with 23 chromosomes. There are 5 stages of mitosis I think and those are interphase, prophase, metaphase, anaphase and telophase.

The first phase, interphase, is the phase where the parts of the cell is still complete and the chromosomes are still coiled. Prophase then comes in, the spindle fibers become visible,the chromosomes become uncoiled, and the nuclear membrane degenerates. The next phase is metaphase where all the chromosomes go to the equatorial plate or to the middle line of the cell. Then anaphase is next, where the spindle fiber attaches to the chromosomes and pulls then to the opposite ends making the chromosomes split up. Then, the last is telophase wherein the two daughter cells are formed.

This topic is an explanation that I learned from our teacher, Mr. Manalo. We all enjoyed this topic since we were all very participative that time.
