Dear Ashley & Xavier how does cell division? And what is it?
Xavier: Mitosis is a process of nuclear division in eukaryotic cells that occurs when a parent cell divides to produce two identical daughters cells. Also during cell division, mitosis refers specifically to the seperation of the duplicated genetic material carried in the nucleus
Ashley: The first step in cell division is Prophase which is when the chromosomes become visible and the spindle fibers emerge from centrosomes. Also the nuclear breaks down and centrosomes move toward opposite poles. Xavier: This leads to Prometaphase and what happens is this stage is that the chromosomes continue to condense then the mitotic spindle microtubules attach to kinetochores .
Ashley: now its metaphase and this is when all the chromosomes line up in the middle. Also each sister chromatid is attached to a spindle fiber originating from opposite poles.Xavier: now, remember Damarius this is only the beginning .....because now we are at the stage called Anaphase where the chromosomes separate from each other and the sister chromatid are now called chromosomes which are pulled toward opposite poles also certain spindle fiber to being to elongate the cell.
Ashley: keep in mind that this is forming the cells now we are in the phase called Telophase and the chromosomes have arrived at opposite poles to begin to decondense and the nuclear envelope surrounds each set of chromosomes and the mitotic spindle fibers break down and the fibers being continue to push poles apart Xavier: Lastly in Cytokinesis the two cell spilt completely such as in a animal cell the cleavage furrow separates the daughter cells and in plant cells the cell plate, the precursor to a new cell wall, separates the daughter cells
