Summary Introduction

To review:

The phage DNA containing the restriction site evades the restriction-modification screening system of its host.

Introduction:

A system present in cells to distinguish between self DNA (deoxyribonucleic acid) and foreign DNA is the restriction-modification system. It involves cleaving of foreign DNA at specific restriction sites and methylation of self DNA. The bacteria produce certain specialized enzymes called restriction endonucleases to identify as well as cleave the DNA at specific sites.

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.
