Practice Quiz 1. State the general HYPOTHESIS being tested (or the question being asked) by the experiments described by Mukouyama, et. al., in their CELL article. (4 pts). Peripheral sensory nerves determine (i.e., cause or are required and sufficient to determine) the pattern of arterial differentiation in mouse embryonic limb skin. 2. Consider the following experiment: Step 1: Samples of normal breast epithelial cells and breast epithelial cells from cancer patients were reacted with labeled antibodies directed against the receptor protein, erbB2.

Unformatted text preview: Step 2: The amount of antibody bound by the two cell samples was compared. Describe the predicted RESULTS of this experiment. (4 pts) When compared, more antibody is bound (indicating more erbB2 receptors present) to the cancer cell samples than to the normal cells. State the CONCLUSION that can be drawn from these results. (in stating your conclusion, use the appropriate terminology from the Rules of Evidence). (4 pts) It is plausible that over expression of erbB2 receptor protein is involved in , or may even cause, cancer cell behavior....
