Chapter 15, Problem 18Q
Summary Introduction

To explain: The reason why the mutant antitrypsin protein causes disease in the normal individual but the mutant antitrypsin synthesized in the laboratory is active as the normal antitrypsin.

Concept introduction: Antitrypsin is a protein that inhibits certain proteolytic enzymes like proteases. It is normally secreted to the bloodstream by the liver cells.  Deficiency of antitrypsin is a hereditary disorder that causes lung and liver diseases and the most common cause of lung disease in the children. Mutation occurs in the antitrypsin gene and leads to over production of proteases, and it causes lung and liver diseases.

If using animals in medical experiments could save human lives, is it ethical to do so? In your answer, apply at least one ethical theory in support of your position.
You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?
You decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.
