S phase (Synthesis Phase) is the phase of the cell cycle in which DNA is replicated, occurring between G1 phase and G2 phase. Since accurate duplication of the genome is critical to successful cell division, the processes that occur during S-phase are tightly regulated and widely conserved. See more Entry into S-phase is controlled by the G1 restriction point (R), which commits cells to the remainder of the cell-cycle if there is adequate nutrients and growth signaling. This transition is essentially irreversible; after passing the … See more Throughout M phase and G1 phase, cells assemble inactive pre-replication complexes (pre-RC) on replication origins distributed … See more Free histones produced by the cell during S-phase are rapidly incorporated into new nucleosomes. This process is closely tied to the replication fork, occurring immediately in “front” and “behind” the replication complex. Translocation of MCM helicase along … See more During S-phase, the cell continuously scrutinizes its genome for abnormalities. Detection of DNA damage induces activation of three canonical S-phase "checkpoint pathways" that delay or arrest further cell cycle progression: 1. The … See more Since new DNA must be packaged into nucleosomes to function properly, synthesis of canonical (non-variant) histone proteins occurs alongside DNA replication. During early S-phase, the cyclin E-Cdk2 complex phosphorylates NPAT, a nuclear coactivator … See more Immediately after division, each daughter chromatid only possesses half the epigenetic modifications present in the paternal chromatid. … See more • S phase index (SPI) • S-fraction or S-phase fraction (oncology/pathology prognosis) • Restriction point See more WebMay 8, 2024 · During the DNA synthesis (S) phase, the cell replicates its chromosomes.
