Neural tissue results when inducing factors
A) block the action of BMP.
B) promote the action of BMP.
C) block the action of sonic hedgehog.
D) promote the action of sonic hedgehog.

Question

Quizplus · Accepted Answer

BMP (bone morphogenetic protein) is a signaling molecule that promotes the formation of non-neural ectoderm. If its action is blocked, the ectoderm will instead become neural tissue. Therefore, inducing factors that block the action of BMP can result in the formation of neural tissue.
