Prophaseis the first phase of mitosis. During this phase, the chromosomes inside the cell's nucleus condense and form tight structures. In fact, the chromosomes become so dense that they appear as curvy, dark lines when viewed under a microscope (Figure 1). Because each chromosome was duplicat...
Features of higher-order chromatin organization—such as A/B compartments, topologically associating domains and chromatin loops—are temporarily disrupted during mitosis1,2. Because these structures are thought to influence gene regulation, it is important to understand how they are re-established after...
Our results show that B-Raf was the critical MEK kinase required for M phase activation of the MAPK pathway. Consistent with this, B-Raf was activated and underwent hyperphosphorylation in an M phase-dependent manner. Interestingly B-Raf hyperphosphorylation at mitosis occurred, at least in part,...
Chalkiness is a common phenotype induced by various reasons, such as abiotic stress or the imbalance of starch synthesis and metabolism during the development period. However, the reason mainly for one gene losing its function such as NAC (TFs has a larg
Timed degradation of initiation factors avoids the re-replication of DNA once S phase starts. DNA replication begins at the exit of mitosis and at early G1 when the origins of replication are recognized and bound by the hexameric Origin Recognition Complex (ORC) [39]. During the G1 and S ...

cells with disorders such as polyploidy and mitotic abnormalities associated with damage to the mitotic spindle, including c-mitosis, as well as lagging chromosomes were found. Genotoxic effects were associated with the abundance of cyanobacteria, which, in turn, depended on the composition of aquatic...
Due to the possibility of side effects when using allogeneic materials, more and more hopes are being placed on autologous materials such as platelet-rich plasma and platelet-rich fibrin. C-reactive protein (CRP), which is an acute phase protein, appears in the blood as a consequence of infla...
