The process of DNA replication is highly conserved throughout evolution. Investigation into the replication machinery of simple organisms has helped tremendously our understanding of how the process works in human cells. The principles uncovered in simpler organisms extend uniformly to eukaryotic organisms. First, DNA replication occurs only in one direction (5’ to 3’). Second, DNA unwinding and DNA polymerization have to be coordinated to avoid formation of large single stranded (ss) DNA regions. Third, the presence of ssDNA is a checkpoint trigger. These rules are the fundamental basis for guaranteeing that the genetic information is properly duplicated and transmitted to the next generation.

The division cycle of most cells consists of four coordinated processes: cell growth, DNA replication, distribution of the duplicated chromosomes to daughter cells, and cell division. In bacteria, cell growth and DNA replication take place throughout most of the cell cycle, and duplicated chromosomes are distributed to daughter cells in association with the plasma membrane. In eukaryotes, however, the cell cycle is more complex and consists of four discrete phases. Although cell growth is usually a continuous process, DNA is synthesized during only one phase of the cell cycle, and the replicated chromosomes are then distributed to daughter nuclei by a complex series of events preceding cell division. Progression between these stages of the cell cycle is controlled by a conserved regulatory apparatus, which not only coordinates the different events of the cell cycle but also links the cell cycle with extracellular signals that control cell proliferation.
5. S Phase: What Happens During this Subphase of the Cell Cycle?
Mar 28, 2019 · Once the cell enters S phase, it is destined to complete cell division, no matter what. Because the S phase is the major checkpoint, the cell ...
The S phase of the cell cycle is part of interphase, when the cell prepares for mitosis. During S phase, the cell replicates its DNA and builds the centrosome. It is regulated by interplay between genes. Replicated DNA must be proofread to ensure it is error-free to avoid disease.
