What is the role of helicase in the S phase?

Background & Aims: The G1/S-phase controlling mechanism known as the RB pathway is commonly deregulated in human malignancies. Here, the abundance and ... In the first phase (G1) the cell grows and becomes larger. When it has reached a certain size it enters the next phase (S), in which DNA-synthesis takes place. E.g. antimetabolites such as methotrexate work in the S phase (synthesis phase) of the cell cycle. Intravenous antineoplastic drugs are administered in the ...

In addition, caspase-2-deficient cells have a higher frequency of stalled replication forks, decreased DNA fiber length, and impeded progression ... Actively dividing eukaryote cells pass through a series of stages known collectively as the cell cycle: two gap phases (G1 and G2); an S (for synthesis) ... The 5-bromo-2′-deoxyuridine (BrdU) labeling of cells followed by antibody staining has been the standard method for direct measurement of cells in the ... Jan 29, 2024 ... Metastasis in ovarian cancer typically occurs through three ... induces apoptosis and cell cycle arrest at the S phase in. SKOV-3 ... 32 What happens during the S phase? DNA synthesis or replication. 33 Each chromosome originally is made of how many DNA molecules and how does this molecule ... Then, at a critical point during interphase (called the S phase), the cell duplicates its chromosomes and ensures its systems are ready for cell division. If ...
