Summary Introduction

To review:

Production of unlimited B cell receptors (BCRs), T cell receptors (TCRs) and antibodies by recombinant DNA (deoxyribonucleic acid) technology.

Introduction:

There are millions of diverse TCRs, BCRs and antibodies in our body. All of them are highly specific for a particular epitope. TCR consist of two α chains and two β chains whereas BCR and antibody consist of two identical heavy chains and two identical light chains. All three of them contains variable regions and constant regions. Ability to recognize a specific epitope is based on the fact that they have unique variable region for every epitope, leading to diversity in TCRs, BCRs and antibodies.

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.
