Describe how cell cycle is regulated

Through the phosphorylation, Cdks signal the cell that it is ready to pass into the next stage of the cell cycle. As their name suggests, Cyclin-Dependent protein Kinases are dependent on cyclins, another class or regulatory proteins. Cyclins bind to Cdks, activating the Cdks to phosphorylate other molecules.

Ecological footprint is determined by measuring carbon dioxide emissions for a given region.
