And here we are folks, Cytokinesis: The final stage of the M Phase, and the last part in the endless loop that is the cell cycle. As a result of Mitosis, two nuclei with identical sets of chromosomes are formed within the cytoplasm of a single cell. All that remains to form two brand new, genetically identical cells is Cytokinesis, the division of the cytoplasm itself. Cytokinesis usually occurs at the same time as Telophase. In most animal cells, the membrane is drawn inward until the cytoplasm is pinched into two nearly equal parts. This process of cleavage leaves two parts each with its own nucleus and cytoplasmic organelles, the two daughter cells. In plant cells, the cell plate forms at the equator, midway between the divided nuclei. The cell plate gradually develops into a separating membrane and a cell wall then begins to appear in the cell plate.
That is the end of Cytokinesis and the M Phase, leaving two daughter cells to start again and repeat the whole process themselves. They once again grow and replicate DNA during Interphase and then divide into two more daughter cells during the M Phase just so they can do it all over again!!!.
Congratulations! You have just read all about the wonderful cell cycle. That is, if you actually read any of that. Well, assuming you did, you should know all you would ever need or truly want to about the life of a cell. They grow, the replicate DNA, and they split, to do it all again from the beginning. It's a vicious cycle. Ah well, if you missed anything, I'd suggest going back to the beginning here on the Main Page.
