Every high school biology class learns about the tiny cells that comprise our bodies, as well as about many of the diverse actions that they perform. One of these actions is called mitosis, the series of steps through which a cell divides itself into two daughter cells, each of which has the same genetic material. Mitosis involves copying or "replicating" each of the cell's DNA-containing chromosomes, and then separating them so that each of the two newly created cells has a complete set of chromosomes, just like the parent cell. Since each chromosome carries distinct genes, the daughter cells need to have all of them, and it is also damaging for the daughter cell to have too many of any of them. Errors in mitosis can lead to cancer and other diseases, so understanding every detail of cell division is of great interest beyond basic scientific discovery. https://phys.org/news/2015-09-decoding-cell-division-mysterious-spindle.html Cell & Microbiology Thu, 17 Sep 2015 12:00:04 EDT news361703273 The last step of the cell cycle is the brief but spectacularly dynamic and complicated mitosis phase, which leads to the duplication of one mother cell into two daughter cells. In mitosis, the chromosomes condense and the nucleus breaks down. https://phys.org/news/2009-02-scientists-deconstruct-cell-division.html Sun, 08 Feb 2009 13:43:11 EST news153322908
