A Chemical Approach To Illustrate the Principal of Signal
... Introduction In nature, cellular functions are propagated by cascades of molecules, which interact with one another for signal transduction. Generally, the sequential process is initiated by the binding of an extracellular signal to a receptor culminating in one or more specific cellular responses ...
