Cell Division

Cell Division Cell division is the process by which a living cell proliferates from one cell to two cells.

The cells before division are called mother cells, and the new cells formed after division are called daughter cells. Generally, it includes two steps: nuclear division and cytokinesis. During mitosis, the mother cells pass the genetic material to the daughter cells. In single-celled organisms, cell division is the reproduction of individuals. In multicellular organisms, cell division is the basis of individual growth, development, and reproduction. Little is known about the division of prokaryotic cells, and only a few specific understandings are about the division of a few bacteria.

Prokaryotic cells have neither a nuclear membrane nor a nucleolus. Only a circular DNA molecule constitutes a nuclear region, also known as a pseudonuclei, which has a nuclear-like function.

The nuclear molecule of the quasi-nucleus is either attached to the plasma membrane or connected to the plasma membrane formed by the intrusion of the plasma membrane. The plasma membrane is also called the inter-body. The replicated DNA was also copied into two. Later, the two interstitials gradually leave due to the growth of the plasma membrane therebetween, and the two DNA molecules connected to them have then pulled apart, and each DNA loop is connected to an inter-body. The cell membrane grows in the center between the two DNA loops that are pulled apart, forming a membrane that finally divides one cell into two cells. Eukaryotic cells can be divided into mitosis, meiosis, and amitosis according to the condition of nuclear division. Mitosis is the basic form of eukaryotic cell division. Meiosis is the process of dividing the chromosomes into germ cells.
