The Cell Cycle
|
|
The second phase of Mitosis, the nuclear membrane disappears completely. The spindle fiber fully develops and attach to the centromeres of the chromosomes. Also, the chromosomes align at the center of the cell.. The Midpoint on a chromosome where the spindle fibers attach during cell division.. The combination of DNA and proteins that make up the contents of the nucleus of a cell.. A contains the replicated DNA of each individual chromosome.. The third step of Mitosis, During this time, the cell's centromeres divide and it's spindle fibers shorten. The chromatids separate and move to the opposite sides of the cell. The separated chromatids are now called chromosomes. .
