Summary Introduction

To explain:

The reason STRs may be used for identification.

Given:

Human genomic short tandem repeats (STRs) are specific gene sequences containing base pairs that are repeatedly arranged.

Introduction:

The human genome is full of repeated DNA sequences. These repeated sequences come in various sizes and are classified according to the length of the core repeat units, the number of contiguous repeat units, and/or the overall length of the repeat region. DNA regions with short repeat are named Short Tandem Repeats (STR). STRs are found surrounding the chromosomal centromere. STRs have proven to have several benefits that make them especially suitable for human identification.

"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?
