How do histone modifications affect origin firing?

... during the S-Phase of the cell cycle. Measurement of DNA synthesis is therefore essential for research in many scientific fields, such as assessing cell ... Not all cells undergo mitotic phase. Cells in the G0 phase are not actively preparing to divide. The cell is in a quiescent (inactive) stage that occurs when ... Jul 8, 2008 ... Cyclin D/CDdk4–Cdk6 activity occurs in mid-late G1 phase, upstream of Cdk2/cyclin E activity. Under conditions favouring proliferation, the ... The expression of apoptosis-related and cell cycle–related proteins in leukemia cells was analyzed through western blotting. The synergistic effect of the Aza ...

Progress in plant cell cycle research is highly dependent on reliable methods for detection of cells replicating DNA. Frequency of S-phase ... During G1 phase, growth-dependent cyclin-dependent kinase (CDK) activity promotes DNA replication and initiates G1-to-S phase transition. 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 ... DNA is replicated during the S phase of.
