Cell cycle diagram Phases of the cell cycle and mitosis DNA Biology Diagrams Cell cycle is the name we give the process through which cells replicate and make two new cells. 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 Actively dividing eukaryote cells pass through a series of stages known collectively as the cell cycle: two gap phases (G1 and G2); an S (for synthesis) phase, in which the genetic material is duplicated; and an M phase, in which mitosis partitions the genetic material and the cell divides. G1 phase. Metabolic changes prepare the cell for division. At a certain point - the restriction point
The cell cycle is a cycle of stages that cells pass through to allow them to divide and produce new cells. It is sometimes referred to as the "cell division cycle" for that reason.

It occupies around 95% time of the overall cycle. The interphase is divided into three phases:- G1 phase (Gap 1) - G1 phase is the phase of the cell between mitosis and initiation of replication of the genetic material of the cell. During this phase, the cell is metabolically active and continues to grow without replicating its DNA. The cell cycle is the sequence of events occurring in an ordered fashion which results in cell growth and cell division. G0, G1, S, G2, M.
Cells on the path to cell division proceed through a series of precisely timed and carefully regulated stages of growth, DNA replication, and division that produce two genetically identical cells. The cell cycle has two major phases: interphase and the mitotic phase. During interphase, the cell grows, and DNA is replicated. During the mitotic phase, the replicated DNA and cytoplasmic contents

Explore how the cell cycle control system regulates cell division through key phases, proteins, and checkpoints to maintain genomic stability and prevent errors. The cell cycle Figure 1. Hand drawn images of dividing cells. From Zellsubstanz, Kern und Zelltheilung, by Walther Fleming, 1882. If living cells are observed under the microscope, they visibly change in morphology (size and shape) as they prepare for and then undergo cell division. One of the first biologists to observe this was Walther Fleming, who developed methods for staining cells that 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
