Document Summary

Kinesin and attached to a microtubule to move toward the posterior wall. An example of this is the ectoderm has a positive affinity for the mesoderm and a negative affinity for the endoderm. They can situate themselves how they are meant to be. If a,b, and c induce d, it allows d to more fully differentiate. For example, source of dermal mesenchyma is wing feather, with wing epiderma becomes a wing: genetic specificity: mesenchymal tissue can only instruct epithelial tissue as far as the genome allows. After that, the ras goes from the gdp bound inactive to gtp bound active state. Gap (gtpase activating protein) hydrolizyzes gtp bound ras to the inactive form. Raf activate mek kinase, mek activates erk kinase, and erk enters nucleus and phosphorylates transcription factors: rtk ligand goes to receptor and travels down the river. Gap in the river and they need to adapt to the protein sos connected to the gnrp by the rtk.
