Introduction:

In molecular biology, the central dogma describes the formation of polypeptide chain from the template DNA strand through the intermediate formation of mRNA.

Transcription Translation

DNA —- ———–> mRNA – ———-> polypeptide

The DNA contains the information for the given polypeptide in the form of specific sequences of codons. The codon is the triplet of nitrogen bases coding the specific amino acids. These amino acids are bound together by peptide bond to form polypeptides.

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.
