The Cell Cycle (and cancer) [Updated]

The video explores cell theory, emphasizing that all living things are made of cells. It explains how multicellular organisms grow through cell division, specifically mitosis and cytokinesis. The video highlights the importance of regulated cell division, noting that uncontrolled division can lead to cancer. It delves into the cell cycle, detailing phases like interphase and M phase, and the role of checkpoints in ensuring proper cell function. The regulation of the cell cycle by proteins such as cyclin and Cdk is discussed, along with the concept of apoptosis. The video concludes with a look at the G0 phase, where some cells remain without dividing.
