Nuclear Division

Cells can grow and proliferate. Cells proliferate by splitting their genes (genetic information) and transferring them to daughter cells. The nucleus always divides before the remaining cells divide. Therefore, each daughter cell contains its own nucleus. The nucleus controls cellular activity through genetic material DNA. The cells in the body are identical except for one gametogenic gamete Zygote. This is the cell formed when your parents' two gametes fuse.

Cell division involves distributing the same genetic material DNA to two daughter cells. It consists of two stages: fission and subsequent cytokinesis. Nuclear fission separates genetic material in the nucleus and cytokinesis divides the cytoplasm. There are two types, mitosis and meiosis. During mitosis or meiosis, the entire process begins with a closely rounded body of genetic material (chromatin), agglomeration (shortening and thickening) to the chromosome. Each chromosome consists of two identical halves, called sister chromatids, joined by centromere. Each chromatid consists of a single tightly packed DNA molecule that is the genetic material of the cell. In diploid cells, there are two copies of each chromosome, forming pairs called homologous chromosomes. In a pair of homologous chromosomes, one homolog is from the female parent and the other from the male parent.

Mitosis is the process of fission in living cells through which the chromosomes of living cells are reproduced exactly and the separated two parts are given to the daughter nucleus. In this process, the two daughter cells undergo a similar chromosomal composition with the same number of chromosomes as the mother cells. Mitosis consists of four main stages. Mitosis occurs in somatic cells (somatic cells). These stages are Premid, Late and Final. During the interim period, the cell becomes inactive most of the time. Indeed, the cells are experiencing normal cellular processes and all metabolic activity. At the final stage of intercellular division, the cells prepare for cell division, but sometimes the chromosomes are replicated at this stage. This period consists of three phases, Growth 1, S phase (DNA synthesis), and Growth 2. During proliferation, newly formed cells synthesize materials for cell proliferation. In S or DNA synthesis DNA is replicated
