Eukaryotic cell division is a lot differnt from bacterial cell sivision. First each chromosome must be copied exactly.
Then the chromosomes must be sorted out so that each new cell gets a complete set. Finally the cell can divide in half.
There are two processes that have evolved that make it possible for eukaryotic cells to divide sucessfully.Those two
processes are mitosis and cell division. Mitosis is the process when the bucleus of a eukaryotic cell divides to form two
nuclei, each containing a complete set of the cell's chromosomes.
The first stage is Interpahse. Cromosomes are nto yet visible. The DNA of each bhromosome consits of two identical strands.
The second stage is Propahse. This is when mitosis begins. The chromosomes coil into short fat rods. The nuclear envelope
breaks up and a network of protein cables called spindle fibers assemble across the cell.
The thrid stage is Metaphase. Chromosomes attach to the spindle fibers and line up in the middle of the cell.
The fourth stage is Anaphase. Each chromatid seperates from its identical copy. Chromosomes are pulled to the opposite
sides of the cell. The spindle fibers begin to break down.
The fifth stage is Telephase. The nuclear envelope forms around each set of chromosomes. The chromosomes uncoil so that
the proteins can be bullt. The spindle fibers disappear.
The first five stages are easy to remember. All you have to do is remember 'IPMAT'.
The last stage is Cytokinesis. This is when the cytoplasm is pinched in half, forming to new, identical cells.
