Cyclins and cyclin-dependent kinases (CDKs) are really important for controlling the cell cycle. Let me explain how they work:
Cyclins: These are special proteins that help decide when different parts of the cell cycle should happen. They are made at certain times and then broken down after they are used. This way, the cell cycle moves forward only when everything is just right.
CDKs: These are enzymes, which are types of proteins that speed up reactions in the cell. They need to attach to cyclins to become active. Once they are active, CDKs can add a phosphate group to other proteins. This process helps the cell move through important checkpoints.
Checkpoints: Checkpoints are like safety checks during the cell cycle. The teamwork between cyclins and CDKs helps keep track of the cell's health. They make sure the DNA is okay and that the cell is ready to divide.
So, in short, cyclins and CDKs work together to make sure everything in the cell cycle goes smoothly and safely!
