Summary Introduction

Introduction:

The environment is composed of a variety of organisms. Animals are the most complex living organisms. They are eukaryotes as they contain a well-defined nucleus enclosed in a nuclear membrane. Animals do not contain a cell wall and they cannot prepare food. All animals are heterotrophs as they depend on other organisms for their food. Cnidarians are the animals that live in marine areas.

"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?
