CELL DIVISION I.: MITOSIS
Prokaryotes are divided by simple fission. BUT eukaryotic
cells of the body divide by cell division called mitosis.
CELL CYCLE of a cell consists of different phases. In the gap
phases (G1, G2) the cell prepares for the next coming phase. In
S phase, DNA synthesis (replication) occurs, in the M phase
the cell divides by mitosis.

MICROTUBULES IN CELL DIVISION
End of mitosis - separation of the two
daughter cells (cytokinesis)
During mitosis, from one diploid (2n) cell two diploid (2n) daughter
cells are formed.
