The satellites are able to monitor the whole planet, thus through them it can easily be seen where the air masses are moving, what type of air masses are moving towards where, their speed of the air masses, is there clouds, and if there is where are they moving, formation of large storms etc. ll of these information from the monitoring of the satellites go to the weather stations, where the weather forecasts are made, and than through the media reach the people all over the world.
Through 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 of regulatory proteins. Cyclins bind to Cdks, activating the Cdks to phosphorylate other molecules.
