What are some of the research questions that are still being investigated regarding the S phase?

... phases: M, G1, S, and G2. M phase (mitosis) is usually followed by cytokinesis. S phase is the period during which DNA replication occurs. The cell grows (more. occurs. In principle, th this pathway operation. Central to and probab ... to those seen late in S and G2 phases of the cell cycle. It is not clear at ... Feb 2, 2025 ... DNA is replicated during S phase.
