Expert Solution & Answer

Explanation of Solution

In 1950, the biochemist Erwin Chargaff and his colleagues found that DNA samples from different sources exhibited certain regularities with respect to the abundance of the different nucleotides. The Chargaff’s rule states that the amount of adenine is equal to the amount of thymine and the amount of guanine is equal to the amount of cytosine but the amount of other nucleotides was not equal. Thus, this relationship shows that the total amount of purine is equal to the total amount of pyrimidine.

"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?
