A Basic Description of the Function of Morphogens is That

Question

A basic description of the function of morphogens is that they:
A) stimulate the formation of the ectoderm.
B) affect the course of local development.
C) kill cells during development.
D) stop all embryonic growth.

Accepted Answer

Morphogens are signaling molecules that affect the course of local development, providing positional information to cells in developing organisms. They often work through gradients, with higher concentrations specifying one cell fate and lower concentrations specifying another. They do not stimulate the formation of any one specific tissue layer or kill cells during development, nor do they stop all embryonic growth.
