Mitosis: During mitosis, the chromosomes in a cell are duplicated. Then the chromosomes will split up to go to identical daughter cells. This movement of chromosomes is highly coordinated, ensuring each new dau
Interkinesis is also known as interphase II which occurs during meiosis. During this phase, the cell is in between meiosis I and meiosis II and is...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your tough...
Prophase is 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 duplic...
Here, weshow that loss of NEIL3 causes anaphase DNA bridging because of telomere dysfunction. NEIL3 expression increases during S phase and reaches maximal levels in late S/G2. NEIL3 co-localizes with TRF2 and associates with telomeres during S phase, and this association increases upon ...

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...
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 ...
S phase, or synthesis phase, is the time during which the cell copies its DNA in preparation for mitosis. Since DNA does not exist by itself in the nucleus but is packaged by proteins, new packaging proteins must also be made to wrap the copied DNA. These package proteins are called hist...

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,...
