Chapter 4, Problem 10TYU
Summary Introduction

To review:

The reason the way catalytic abilities of DNA (deoxyribonucleic acid) are restricted by its secondary structure when compared to RNA (ribonucleic acid). The reason behind the catalytic nature of RNA.

Introduction:

DNA and RNA are macromolecules present in the cell. These macromolecules contain information to form proteins that carry out all the necessary functions of the cell. According to the Central Dogma, DNA is self-replicating and can also pass down the genetic information to an RNA strand. This occurs by a process called transcription. The RNA molecule further forms proteins by the process of translation.

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.
