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.
