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 throughout the genome. During S-phase, the cell converts pre-RCs into active replication forks to initiate DNA replication. This … See more Immediately after division, each daughter chromatid only possesses half the epigenetic modifications present in the paternal chromatid. The cell must use this partial set of … See more During S-phase, the cell continuously scrutinizes its genome for abnormalities. Detection of DNA damage induces activation of three … 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 … 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 • S phase index (SPI) • S-fraction or S-phase fraction (oncology/pathology prognosis) • Restriction point See more WebJan 23, 2013 · Additive synthese waveform generator. Every randomly shaped waveform can be composed by adding one ore more sine waves signals with each a different frequency, phase and amplitude. This is also called additive synthesis. The frequency range consists of the fundamental and his harmonics. The wave shape in the tool beneath can …

SPF is at its peak when the cell cycle is transiting from G1 phase to the S-phase. The SPF is at its lowest during the cell cycle once the cyclin subunits are used up, and broken down. Therefore, everything that happens during mitosis … WebS-Phase. In der S-Phase, kurz für Synthese-Phase, findet eine DNA-Replikation statt.
