Problem:
Explain the answers of the question;
Question 1: What cell fate is induced in animal hemisphere cells of the amphibian embryo by BMP signaling?
Question 2: What is the mode of action of the neural inducing molecules chordin and noggin?
Question 3: Briefly describe the anatomical structure of the central nervous system of a tadpole stage amphibian embryo.
Question 4: What is the evidence that neural tissue induced by noggin differs from the neural tissue induced by the combined action ofnoggin and FGF?
Question 5: Compare and contrast the effects of BMP and FGF signalling on the activity of the Smad1 protein.
