What initiates the activation of the MAP Kinase Pathway?

• Binding of growth factors to receptor tyrosine kinases

• Activation of transcription factors

• Phosphorylation of ERK

• Dimerization of DNA

Which protein is activated by RAS in the phosphorylation cascade?

• SOS

• RAF

• MEK

• ERK

What is the ultimate result of the MAP Kinase Pathway activation?

• Inhibition of cell growth
