Detailed explanation-1: -(sel SY-kul) The process a cell goes through each time it divides. The cell cycle consists of a series of steps during which the chromosomes and other cell material double to make two copies. The cell then divides into two daughter cells, each receiving one copy of the doubled material.
Detailed explanation-2: -In eukaryotes, the cell cycle consists of four discrete phases: G1, S, G2, and M. The S or synthesis phase is when DNA replication occurs, and the M or mitosis phase is when the cell actually divides. The other two phases-G1 and G2, the so-called gap phases-are less dramatic but equally important.
Detailed explanation-3: -The cell cycle is the regular pattern of growth, DNA duplication, and cell division that occurs in eukaryotic cells.
Detailed explanation-4: -G1 is followed by S phase (synthesis), during which DNA replication takes place. The completion of DNA synthesis is followed by the G2 phase (gap 2), during which cell growth continues and proteins are synthesized in preparation for mitosis.
