Answer to Problem 1FIB

Correct answer:

The genetic material of all living organism is DNA, which is contained in chromosomes. A gene is a part of a chromosome found at a specific place or locus. Alternate forms of gene are called alleles.

Explanation of Solution

DNA plays an important role in everyone’s life. DNA is the genetic material that is present inside the nucleus of the cell. Short segment of DNA are called as genes. These genes are responsible for the features that an individual inherit from his parents. Genes are the segments that are used in research nowadays. Genes are present on the chromosomes. Chromosomes are present inside the nucleus in compact form. An allele is the different form of gene, which is located at different position or locus.

Conclusion

Thus, all life form has DNA as their genetic material. Different forms of genes are known as alleles.

"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?
