FIG. 5.2. Diagram of typical mitosis (cell division). Note 

 the elaborate mechanisms insuring exact duplication of 

 each chromosome, and exact distribution of the "daughter 

 chromosomes" so that each cell receives one of each kind 

 and thus has exactly the some number and kinds as the 

 original cell had. In the first diagram (upper left) each 

 chromosome is shown as having duplicated itself (indicated 

 by the double lines showing parallel threads). Each chro- 

 mosome shortens, by coiling, and secretes a matrix about 

 itself prior to the actual separation of the daughter chro- 

 mosomes (formed by the earlier duplication) in anaphase 

 and later stages.
