Q. Your friend is trying to generate an in vitro system for studying the formation of COPII vesicles. He finds that to get well-organized vesicle budding from artificial membranes, he needs to add the coat proteins, the Sar1 GTP-binding protein, the GTPase-activating protein (GAP) for Sar1, and GMP-PNP (a nonhydrolyzable […]

Suppose that in your lab you occasionally get mice that have some sort of bizarre mutation-bent ears. You determine that the bent-ear trait is recessive. You then find out that someone else in your lab has isolated mice with bent ears as well and that they have also determined that […]
