Summary Introduction

To review:

The role of vitamin D in increasing calcium (Ca) level in the body and also the reason for not considering it a vitamin nowadays.

Introduction:

Calcium plays a very important role in keeping the bones healthy and maintaining cell integrity. There is a very low percentage of Ca in the cells and the major proportion is present in the bones. The presence of optimum levels of Ca is very essential as even a slight increase or a slight decrease in the levels affects the nervous system of the body.

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.
