This video provides a detailed explanation of mitosis, the process by which a cell's nucleus divides into two cells with the same genetic information. It covers the different stages of mitosis, from the Profase stage to the Telofase stage, as well as the meiosis process.

  • 00:00:00 In this video, we learn about mitosis, a process by which a nucleus divides into two cells with the same genetic information. It is easy to follow, with just a few steps that you'll soon remember. Mitosis happens near the end of the cell cycle, and is mostly interface (this part, in which the cell does what it is supposed to according to the type of cell it is, is mostly important) followed by mitosis (in which two nuclei are formed from one) and finally, cytokinesis (which starts near the end of mitosis and ends a little after). The cell separates into two cells, each with one of the nuclei that were formed during mitosis. Keep in mind that chromatin, which is the genetic material, is associated with histones (proteins) that can be modified and lead to DNA being wrapped around itself and forming a chromatin molecule. Typical chromosomes have two copies of the same chromatin molecule, which was formed when two strands of DNA were condensed. Mitotic chromosomes have a shape that looks like a X, and when you look more closely, you'll see that each chromosome has two copies of the same chromatin molecule, which were duplicated when they were condensed. Mitosis is
  • 00:05:00 The mitosis has four stages. Some people say that it has five stages, but I will explain the five stages here. PMAT. P stands for Profase. Pro means before. I think the best way to remember what was happening in each stage is by understanding what the name of the little Greek word means. Because all of the "loquesea-fase" names start with "P", it's easier to understand what's happening by understanding what that word means in Greek. Keep in mind that, at first, these strange-sounding names may seem strange, but the scientists who gave them this name also had to study other names, and it would be difficult for them to come up with a good name. And always, in science, when you have to give a name to something, you give it a lot of thought until you find the name that is the best fit. And in this case, the names that are given to what's happening here are names that describe or even describe what is happening. And it's even more obvious when you look at the other two. PMAT: Profase (or Profase and Prometafase, if you
  • 00:10:00 The video explains the mitosis process, from the Profase stage (before the first division of the chromosomes) to the Telofase stage (the completion of the cell's division). It also covers the mitotic checkpoint and the role of microtubules in the process. Finally, the video describes the meiosis process, including the formation of two daughter cells with the same genetic information.
