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 Cell cycle has different stages called G1, S, G2, and M. G1 is the stage where the cell is preparing to divide. To do this, it then moves into the S phase where the cell copies all the DNA. So, S stands for DNA synthesis. After the DNA is copied and there's a complete extra set of all the genetic material, the cell moves into the G2 stage

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.
The Cell Cycle. Mitosis is part of a precisely controlled process known as the cell cycle. The cell cycle is the regulated sequence of events that occurs between one cell division and the next. The cell cycle has three phases: interphase. nuclear division (mitosis) cell division (cytokinesis) The length of the cell cycle is very variable depending on environmental conditions, the cell type and
AQA Mitosis and the cell cycle Biology Diagrams
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 by checkpoints and signals. The cell cycle is the series of events that occur in a cell leading to its division. It consists of interphase and mitotic phase. The cell cycle is a fundamental process in biology that ensures proper growth, development, and reproduction in organisms.
