Skin cells areamong the cells with the highest turnover rate, that is, they divide themselves and create new cells very often. This is a consequence of the intense demands that we pose in our skin, as we sense the world with it! And several times we get some harm that our skin recevies. During interphase, prior to division, the cell has to replicate all its genomic information. SInce it has two create two daughter cells with the same information. So, a complex anabolic display is orchestrated to synthetize a copy of the whole DNA material. When this is done, the cell starts the mitosis (cell division properly speaking). The first stage is prophase, where the nucleus starts to disintigrate, so DNA is realeased to the cytoplasm. By this point, chromosome start to form. The next phase is metaphase, where completely formed chromosomes start to migrate to the cell middle part. This is done, due to microtubles that are polymerized and used as trails to track the chromosomes to center of the cell. Remember, by this time we have a copy of the DNA. The next phase is anaphase, where each pair of chromosomes move to an opposite side, this is also done thanks to the microtubules serving as trails. The final phase is telophase, where the cell membrane starts to split, so it requires a lot of microtubles, and filaments to synthetize so the new (two) cells could be split entirely. By the end of the telophase ww talk about citokinesis, which means "cell formation", and the nucleus starts to reassemble again. Next, cell starts to perform its job.
