Prokaryotic Cell Division, Chromosomes prokaryotic cell division - division by binary fission genome made of single, circular DNA found in nucleoid area replication of DNA begins at specific site and goes bidirectionally around to specific site of termination cell elongates, DNA gets attached to the membrane septum - new membrane growing near the midpoint during division o composed of FtsZ protein ring eukaryotic cells developed mitosis to deal w/ larger, nucleus-enclosed genomes mitosis - occurs differently in different organisms protists - 2 ways o microtubules (w/ tubulin) pass through nucleus membrane tunnels and sets up axis for division (nucleus remains intact) o microtubule spindle forms between centrioles at opposite sides; kinetochore microtubules pull chromosomes to each pole (nucleus remains intact) yeasts - spindle microtubule forms inside nucleus between poles o single kinetochore microtubule attaches to chromosomes, pulls them to each end
