Epidermal Growth Factor is a protein that binds its receptorwith high affinity (low Kd). Choose the most likely order of eventsfor what ensues:

A) G protein activation> tyrosine kinase activity>transcription factors active> map kinase activation and signalamplification
B) G protein activation and signal amplification > mapkinase activation >transcription factors active>tyrosinekinase activity
C) tyrosine kinase activity>G protein activation> mapkinase activation and signal amplification>transcription factorsactive
D) tyrosine kinase activity>Gprotein activation> phosphatase activation> secondmessengers>map kinase activation >transcription factorsactive
