Summary Introduction

Telomerase is an enzyme that adds a sequence of telomere to the chromosomal ends. Eukaryotic cells and the somatic cells contains low concentrations of this enzyme. These enzymes are not used regularly in eukaryotes and therefore, aging resulting in reduction of chromosome length. High concentrations of this enzyme are present in stem cells, cancer cells and germline cells.

"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?
