Summary Introduction

To describe:

How the information is encoded in DNA and RNA and how information flows from DNA to RNA and to proteins.

Introduction:

DNA is the hereditary molecule of all the living and non-living cell. It is made of the polynucleotide chain carrying the genetic information or “gene”. The nucleotides are made up of a ribose sugar attached to a nucleic acid base. The nucleic acids present in DNA are; thymine (T), adenine (A), cytosine (C) and guanine (G). DNA can be single-stranded or double-stranded. Similarly, RNA is also a hereditary molecule in some viruses and other organisms. It may be single or double-stranded. RNA is also assembled as a chain of nucleotides. The nucleotides are made up of a ribose sugar attached to a nucleic acid base. The nucleic acids present in RNA are; adenine (A), cytosine (C), guanine (G), and uracil (U).

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.
