Summary Introduction

To determine:

The reason for the inability of scientists to produce vaccine against HIV and common cold.

Introduction:

Many organisms attack other organisms and cause infectious diseases. All organisms have a well-defined organ system that fights with these pathogens and protect the body from infectious diseases. This organ system is called the immune system. The scientists have discovered a technique in which microbes are used to enhance the immune system. This method is termed as vaccination. The substance that contains weak or attenuated form of microbes to enhance the activity of immune system is termed as vaccine.

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.
