Summary Introduction

Introduction: A skeleton is a structure that provides support and protection and plays an important role in locomotion. Exoskeletons and endoskeletons are the two major types of skeletons found in animals. Endoskeletons in vertebrates provide structural support and protect internal organs. Vertebrate endoskeletons are composed of both cartilage and bone in bony fishes, amphibians, reptiles, birds and mammals.

"One of the symmetry breaking events in mouse gastrulation requires the amplification of Nodal on the side of the embryo opposite to the Anterior Visceral Endoderm (AVE). Describe one way by which Nodal gets amplified in this region." My understanding of this is that there are a few ways nodal is amplified though I'm not sure if this is specifically occurs on the opposite side of the AVE.  1. pronodal cleaved by protease -> active nodal 2. Nodal -> BMP4 -> Wnt-> nodal 3. Nodal-> Nodal, Fox1 binding site  4. BMP4 on outside-> nodal  Are all of these occuring opposite to AVE?
