As expressed in the cell theory: all the cells are formed from preexisting cells. The growth and development of living organisms depends on the growth and multiplication of their cells when a cell divides, the genetic information contained in DNA is precisely duplicated copies are then transmitted to each c 鬵 daughter. In prokaryotes this process s simple division called binary fission. In eukaryotes the DNA is organized into more than one chromosome, with the process of cell division more complex.
Despite differences between prokaryotes and eukaryotes, there are many points in common between both cell division cell, which must pass through four stages: Growth
Despite differences between prokaryotes and eukaryotes, there are many points in common between both cell division cell, which must pass through four stages: Growth
duplication must occur DNA. DNA must be separated
"original" of his "reply" (for it is packaged into discrete units or chromosomes)
cells must separate the two "daughters" which ends with cell division.
These basic processes should occur in both types of cells.
Cell cycle: the cyclical sequence of processes in the life of a eukaryotic cell that retains the ability to divide. Consists of interface, mitosis and cytokinesis. The time required to complete a cell cycle is the time regeneration.
In general, all cells go through two períoos in the course of their cell cycle: INTERFACE
one: is the period during which the cell grows, replicates its DNA and prepares for the next division;
period of division Phase M: is the stage of the cell, leading in turn to two events:

cytokinesis or division of the cytoplasm into two daughter cells.
