During S phase the amount of DNA in the cell doubles because chromosomes are duplicated. As a result, the amount of DNA found in a cell in G2 is significantly higher than that of a cell in G1.
Interphase accounts about 90%of the cycle; during interphase the cell grows and copies its chromosomes in preparation for cell division. Interphase is divided into sub phases: G 1 phase (first gap), the S phase (synthesis), and G 2 phase (second gap). The chromosomes are duplicated only during the S phase. During G 1 phase cell grows until S phase where the cell prepares for the cell division during G 2 phase. Based from human cell, M phase only takes about 1 hour while the S phase occupy about 10-12 hours.
