Summary Introduction

To describe:

The structure of DNA and RNA molecules.

Given:

Structure of DNA differ from RNA molecules.

Introduction:

Deoxyribonucleic acid (DNA) is defined as a molecule which contains the instructions of the organism to develop, live as well reproduce. For the first time, Frederich Miescher in 1869 observed the DNA. Later in 1953, James Watson, Francis Crick, Maurice Wilkins and Rosalind Franklin find out the structure of DNA, the double helical nature. Robert Holley was the first to find out the structure of tRNA. In 1955, Francis Crick proposed adapter hypothesis to explain the structure which carry the amino acids and arrange them in an order in relation to the base sequence in the mRNA.

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.
