Exploring the Cell Cycle: Mitosis and Meiosis

Mr. Anderson's video explains the cell cycle, focusing on mitosis and meiosis. It covers how cells reproduce, the importance of meiosis for sex cells, and the role of cyclins and CDKs in regulating the cell cycle. The video also details the phases of the cell cycle, including G1, S, G2, and mitosis, and compares mitosis and meiosis processes.

What are cyclins?

• Proteins that regulate the cell cycle
