Cell Division

---

Cell division occurs when an original cell splits into two or more cells, referred to as daughter cells. Cell division typically takes place as a component of a broader cell cycle. Each cell breaks by splitting into two, with each parent cell producing two offspring cells. The newly created daughter cells have the potential to divide and expand, leading to a new cell population that derives from the division and growth of one parental cell and its offspring. There are two different forms of cell division, the first being vegetative division, where each daughter cell replicates, called mitosis. The process is meiosis, which splits into four haploid offspring cells. The cell cycle consists of two phases such as Interphase, which is considered a resting stage between consecutive cell divisions, has been revealed by new search to be quite active, while the M phase is the stage in which actual cell division occurs. This phase includes two main steps, such as karyokinesis and cytokinesis. Prior to the cell division, it is necessary for a cell to thoroughly and accurately replicate the genetic material contained in its DNA so that the resulting daughter cells can operate and thrive. This presents a complicated issue due to the significant size of DNA strands. Every human chromosome comprises a lightly double spiral, or helix, where each strand contains over 100 million nucleotides. In prokaryotes, DNA synthesis cycles may start before the completion of prior cycles. In contrast, eukaryotic organisms replicate their DNA precisely one time during a distinct interval between cell division. This phase is called the S (for synthetic) phase. It is followed by a phase known as G2 and preceded by a phase referred to as G1 (which means “first gap”), during which nuclear DNA is not synthesized.
