You generate a transgenic mouse line with a lox-stop-lox sequence upstream of a dominant-negative Notch fused to GFP. Upon crossing this mouse with another mouse line expressing ectoderm-specific Cre, what would you expect for the phenotype of neuronal differentiation in the resulting embryos?
Hair follicle formation is thought to result from a reaction-diffusion mechanism with Wnt and its antagonist Dkk1. How is Dkk1 regulated by Wnt? Describe specific cis-regulatory elements and the net effect on Dkk1 expression.

Identify the areas of the lipid bilayer that are hydrophobic and hydrophilic. Draw a membrane with two transporters: a proton pump transporter that uses ATP to generate a proton gradient, and a second transporter that moves glucose by secondary active transport (cartoon-like is ok). It will be important to show protons moving in the correct direction, and that the transporter that is powered by secondary active transport is logically related to the proton pump.arrow_forward
