What is the role of cyclins in the cell cycle? (2019)

Step 1: Understand that the cell cycle is the process by which a cell grows and divides.
Step 2: Learn that cyclins are special proteins that help control this process.
Step 3: Know that cyclins work by activating other proteins called cyclin-dependent kinases (CDKs).
Step 4: Realize that when cyclins activate CDKs, these kinases can then trigger different stages of the cell cycle.
Step 5: Remember that without cyclins, the cell cycle would not progress properly, leading to issues like uncontrolled cell growth.
