Document Summary

Interphase: the non-dividing phase (cell growth and copying of chromosomes in preparation for cell division: brain, spine, and muscle cells don"t undergo mitosis. In anaphase, sister chromatids separate and move along the kinetochore microtubules toward opposite ends of the cell: non-kinetochore microtubules from opposite poles overlap and push against each other, elongating the cell. In telophase, genetically identical daughter nuclei form at opposite ends of the cell. In animal cells, cytokinesis occurs by a process known as cleavage, forming a cleavage furrow. In plant cells a cell plate forms during cytokinesis, which will form the cell walls of the daughter cells: binary fission, prokaryotes (bacteria and archaea) reproduce by a type of cell division called binary fission. If a cell receive a go-ahead signal at the g1 checkpoint, it will usually complete the s, g2, and m phases and divide. In asexual reproduction (like binary fission), one parent produces genetically identical offspring by mitosis.
