Question
Chapter 6.6, Problem 1C
Summary Introduction
To explain: What can be predicted about the cell signaling mechanism of choanoflagellates and animals as they have similar protein kinases.
Concept introduction: The molecules of signaling pathways such as G protein, protein kinases, and phosphatases have been conserved in different organisms. It would be helpful to communicate with different organism and supposed to be important for cell survival.

Drag the descriptions below to their proper places on the figure to show the sequence of events. When growth factor binds to the receptor, the intracellular domain activates RAS by facilitating exchange of GDP for GTP. When no growth factor is bound to the extracellular receptor, RAS is bound to GDP and is inactive. RAS activates the first of three sequential kinase proteins termed the MAP kinase cascade. Cell proliferation proceeds as the machinery for cell division is set in motion. The end result of the MAP kinase cascade is activation of a transcription factor.
