Summary Introduction

To determine:

The appropriate control for the experiment in which Fleming applied filtered medium from a Penicillium culture to plates of bacteria.

Introduction:

The discovery of antibacterial drug penicillin was by chance as it was discovered by Alexander Fleming due to some mistakes in control measures while culturing a bacterial culture in the lab. Due to mistakes in control measures of the experiment, bacterial culture was contaminated by a Penicillium mold. Fleming observed that no bacterial growth was found near the mold as it prevented bacterial colonies to grow.

"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?
