Chapter 15.6, Problem 4TQ
Summary Introduction

To review:

The reason behind the conversion of ribosyl nucleotides into deoxyribonucleotides and the information about the evolution of nucleic acid that is reflected by this conversion.

Introduction:

Nucleotides are compounds that are made up of a nucleoside group and a phosphate group. These are the fundamental constituting units of both DNA (deoxyribonucleic acid) and RNA (ribonucleic acid). Nucleosides are comprised of a nucleobase along with a five-carbon sugar. Adenine, guanine, thymine, and cytosine are the four nucleotides present in DNA while thymine is replaced by uracil in the case of RNA and the others remain the same.

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.
