Mitosis begins as the long --------of DNA in the nucleus start to------. Already replicated, these threads emerge as double -------, we know as chromosomes. Meanwhile, protein -------grow from the migrating centrioles forming a lattice work of -------. For reasons, scientists don’t fully understand nuclear membrane suddenly--------. With amazing accuracy a spindle from each centriole attaches itself to each of the chromosomes. Assisted by the protein fibers the chromosomes move centrostage. In a microscopic ----of war the spindles pull each chromatid toward opposite poles. Other spindles -----against each other in a rachidian action that stretches the cell. The chromosomes then ---- and the nuclear membranes reform. With mitosis complete, the nuclei and the cytoplasm separate to create two new cells in this ongoing cycle that sustains all life. http://www.youtube.com/watch?v=nPG6480RQo0 it’s a mute video.
