What is the Cell Cycle Biology Diagrams cell cycle, the ordered sequence of events that occur in a cell in preparation for cell division.The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage).The stages G1, S, and G2 make up interphase, which accounts for the span between Phases of the Cell Cycle 1. Gap 0 Phase (G0) Gap 0 phase or G0 phase of the cell cycle is a period of time where the cell is present in a quiescent stage or resting phase, as it neither divides nor grows. The G0 phase can be considered either an extended G1 phase or a separate phase-out of the cell cycle.
The most basic function of the cell cycle is to duplicate accurately the vast amount of DNA in the chromosomes and then segregate the copies precisely into two genetically identical daughter cells. These processes define the two major phases of the cell cycle. DNA duplication occurs during S phase (S for synthesis), which requires 10-12 hours and occupies about half of the cell-cycle time in

It is the first phase of the cell cycle, recognized by the growth period where the chromosome gets duplicated as the cell prepares for division. Interphase happens between one cell division or mitotic (M) phase and the next. It is the longest part of the cell cycle involving three sub-phases. The typical duration of this phase is 23 hours.
Summary. The cell cycle is an orderly sequence of events. Cells on the path to cell division proceed through a series of precisely timed and carefully regulated stages. In eukaryotes, the cell cycle consists of a long preparatory period, called interphase. Interphase is divided into G 1, S, and G 2 phases. Mitosis consists of five stages Learn about the cell cycle, the cycle of stages that cells pass through to divide and produce new cells. Find out the functions, phases, and examples of the cell cycle, and how it is regulated in different organisms.

Overview of the Cell Cycle Phases. The two broad phases of the cell cycle are interphase and mitosis. During interphase, cells grow, replicate their DNA and organelles, and prepare for division. Interphase steps are the first gap phase (G 1), the synthesis phase (S), and the second gap phase (G 2). Cells divide during mitosis (M).
