Researchers searched for an activator of neural tissue formation. What is the real pathway for this developmental phenomenon?
a. Neural tissue formation occurs via BMP inhibition by proteins secreted from the organizer.
b. Noggin activates ectoderm to become neural tissue.
c. Nodal activation induces mesoderm to make neural tissue.
d. Beta-catenin is required for formation of neural tissue.

Group of answer choices
a. control of formation of the dorsal/ventral axis in the chick
b. control of front/back (anterior/posterior) axis formation at the two cell stage
c. hormonal control of development continued after
d. how cells move and adhere to one another to complete developmental changes
e. formation of front/back (anterior/posterior) positional information in limb bud formation
Suppose we would want to have mirrored lateral sides (meaning both the left and right portion are equal) in a chick embryo to see how it would develop. How would we achieve this by manipulating the genes that dictates the development of the organs?
