Summary Introduction

To determine: The purpose of the iris diaphragm.

Introduction: Microscope is an optical instrument that is used in visualizing objects that are too small to be seen with the naked eye. The three basic structures of the microscope are head or the body, the base, and the arm. The major components of the microscope are eyepiece, objective lenses, stage, condenser, iris diaphragm, and coarse focus.

Summary Introduction

To determine: The purpose of a condenser.

e.

Summary Introduction

To determine: The purpose of mechanical stage control.

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.
You implant an FGF10-coated bead into the anterior flank of a chicken embryo, directly below the level of the wing bud. What is the phenotype of the resulting ectopic limb?  Briefly describe the expected expression domains of 1) Shh, 2) Tbx4, and 3) Tbx5 in the resulting ectopic limb bud.
