During the G1 phase all the internal organelles of the animal cell are replicated, during the S phase (the longest phase) all the DNA of the cell is replicated, and during the G2 phase the replicated DNA is checked for mutations. read more
This process is necessary prior to mitosis to ensure that the cell has twice the usual amount of organelles and twice the usual amount of DNA to ensure that two genetically identical diploid cells can be produced when the cell divides by equatoral division in mitosis. read more
Mitosis is a cell division that occurs in animal cells where each mother cell divides into 2 daughter cells. The number of chromosomes in the mother cell is identical to that in each resulting daughter cell. read more
Cell division in animals: mitosis, cytokinesis, and the cell cycle. Cell division in animals is a two-step process involving mitosis and cytokinesis and is set up by interphase. Interphase is a growth period for the cell. read more
