Are there diurnal variations in DNA replication efficiency or the response to DNA damage?

The eukaryotic cell spends most of its "life" in interphase of the cell cycle, which can be subdivided into the three phases, G1, S and G2. Cell division is ... In fact, the accumulation of cells in S phase was found to be a gradual process that occurs over several cell cycles, as shown in Fig. 2 B for ... Mar 24, 2025 ... 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 ( ... It is generally believed that this type of repair occurs preferentially in the late S, G2 and M phases of the cell cycle, when the sister chromatid is ... Two gap phases precede the S and M phases; in G1 the cell prepares for DNA synthesis, and in G2 the cell prepares for the mitotic division that takes place in ... Jul 29, 2019 ... Cell cycle analysis. SSCs from the control group and the heat shock-treated group (43 °C, 45 min) were seeded in 6-well plates at ... Mar 28, 2018 ... Silkworm Pupa Protein Hydrolysate Induces Mitochondria-Dependent Apoptosis and S Phase Cell Cycle Arrest in Human Gastric Cancer SGC-7901 Cells. Sep 25, 2019 ... 8 What happens during S phase of the cell cycle? a. The cell divides b. The cell undergoes its final preparation for division C. The cell ... Figure 1: A cell moves through a series of phases in an orderly manner. During interphase, G1 involves cell growth and protein synthesis, the S phase involves ... Jul 11, 2022 ... ]. The periodic expression of cell cycle regulators occurs in two broad waves of expression, which peak during the G1/S and G2/M phase ...
