the nuclear material in the cell is doubled. As a result, chromosomes in cells consist of two identical chromatids i.e. S Phaseĭuring S phase, also called the synthetic phase, the cell undergoes DNA replication. These signals lead the cell to enter the next phase of the cell cycle, the S phase. At some time during this interphase, the cell receives signals that it should go division again. During this interphase, a cell grows in size, becomes structurally and functionally active, and matures into a parent cell. Once a daughter cell is formed from the parent cell, the G 1 phase of the cell cycle starts. Recall that mitosis is a part of the normal cell cycle. The Cell Cycleīefore jumping to studying the various steps of mitosis, it is important to understand the pre-mitotic events that prepare a cell for mitosis. We will study various steps of mitosis, its regulation as well as its importance in living organisms. It is a process in which a nucleus divides into two daughter nuclei having the same number of chromosomes as the parent nucleus. Mitosis is a type of nuclear division that is a part of the normal cell cycle of most of the cells. Out topic of discussion in this article is mitosis. The division of the nucleus is of two types Meiosis and Mitosis. The process of cell division involves two essential steps, division of the cytoplasm and division of the nucleus. The process of cell division not only gives rise to a new life but is also responsible for transferring the traits of the parent cell into the daughter cells.
It is the process by which new life comes into existence from a pre-existing cell. Cell division is a process of growth and reproduction at a cellular level. The process of cell replication and cell division is essential for the maintenance and continuity of life of an organism. How asexual reproduction occurs by mitosis?.How is chromosome number maintained in mitosis?.What is mitosis, and what are its different stages?.
