Mitosis is the separating of a cell's nucleus while passing on the same chromosomes to each of the two daughter cells. ... Once that occurs, mitosis begins. ... Also, the nucleus begins to breakdown. ... Also, the nucleus begins to reform.

Cell Division - Mitosis, Meiosis1 and Meiosis2 Mitosis defined: is nuclear division that produces two daughter nuclei, each with the same number and kinds if chromosomes as the parental nucleus. ... Mitosis is the process by which the contents of the eukaryotic nucleus are separated into two genetically identical packages. ... Mitosis is divided into four stages, prophase, metaphase, anaphase, and telephase. ... Anaphase is the stage where the centromeres divide. ... Telophase 2 the nuclear membrane reforms, the spindle disappears, and cytokinesis divides the cytoplasm. ...

There are two types of cells: eukaryotic and prokaryotic and these two cell types reproduce or divide in two main ways, either Mitosis or Meiosis. ... An eukaryotic cell nucleus contains a lot of DNA and protein that get together to form a chromosome. ... Other cells divide when they reach maturity through the Mitosis or Meiosis types of cell division. ... Most cells both eukaryotic and prokaryotic divide through the Mitosis processes which is asexual. ... When a cell divides by Mitosis, it makes an exact copy of its DNA and transfers this to a daughter cell, sort of like cloning. ...

Animal cells are known as being Eukaryotic, literally translated as "good nucleus" indicating that the cell consists of many organelles including the nucleus. ... The nucleus also contains chromatin, a condensed complex of DNA and protein which make up chromosomes. ... Outside of these phases in order to divide a cell must replicate the genetic information and the organelles within it. ... Although mitosis and meiosis share some similarities there are some contrasting factors detailed below. ...

In 1882, Walther Flemming discovered chromosomes and mitosis. ... We know that there are 46 chromosomes within the structure of a cell nucleus. ... In the late 1900s, we have discovered new technologies, which enable us to have found the processes of mitosis and meiosis, heterogeneous and homogeneous mixtures (the makeup of a hybrid cross), and many other processes and facts. Mitosis is a process in which the nucleus of a cell is divided in half making two new identical cells. Meiosis is the process of dividing two consecutive cells creating four identical new cells. ...
