Neural Tube.
a. How would over-expression of BMP signaling proteins in thesurface ectoderm adjacent to the developing neural tube affect theformation of the dorsolateral hinge points (DHLPs)
b. Cells in the neural tube show an important change in theexpression of cell adhesion proteins. What cell adhesion proteinstops being produced and what is the effect on neural tube closureif this change does NOT occur?
PLEASE EXPLAIN as much as you can
