Cell division Part 1
Maybe this post will seem boring as it’s a part of biology that reminds you of your typical studies and so on. Well, I’m talking like this cause the same thing had happened to me until I found it interesting. Now let’s go to the point. This topic is about cell division in where I’m going to describe "a little" about it in case of humans & animals. I’ll try to provide the basic concepts rather than going too deep and making things complicated.
Before going to cell division we should at least know that a cell consists of cytoplasm and nucleus. If you think of a broken egg, then the middle yellow circle would be the nucleus and white part you can imagine as the cytoplasm. Like the broken egg, each cell includes only one nucleus and in the nucleus there’re nucleolus, nuclear pore, nuclear membranes, chromosomes that is made of chromatin (DNA, RNA & protein), etc. In human body, there're 46 chromosomes or 23 homologous pairs of chromosomes. Homologous chromosomes are about the same size and contain the same types of genes. One more thing you should know before starting, which is, the plural form of nucleus is nuclei not nucleuses or something. We all know that cell divisions can occur in 3 ways. One is amitosis which can only be found in the unicellular organisms like bacteria, yeast, fungus, ameoba etc. In the process of amitosis cell division, nucleus at first forms into a dumble. Then cytoplasm carries two sides of the dumbbell and directly divides into two daughter cells. These cells are similar to each other.
