• The nuclear membrane breaks down

• DNA replication

• Sister chromatids separate

Which phase of the cell cycle does the cell spend the greatest amount of time in?

How are cyclins and CDKs involved with the cell cycle?

• Cyclins stop the cell cycle from proceeding

• Cyclins and CDKs make up a protein ring used to perform cytokinesis

• Cyclins activate CDKs, which perform the work of cell division

• CDKs are secreted from cells to trigger division in neighboring cells
