To draw: To color sister chromatids and follow their distribution through mitosis and cytokinesis. Introduction: Cell division is a process where the cells during high nutrition conditions give rise to two daughter cells. The cell division is two types: Mitosis and Meiosis. The mitosis is where the cell divides to form exactly two replicas of itself. The meiosis is reduction division where the cell replicates but the chromosome number reduced by half. In both the cases, there is an involvement of the spindle fiber machinery to pull apart the sister chromatids to the two daughter cells equally from the metaphase plate. During cell division, DNA occurs in condensed form and appears as distinct chromosomes. Each chromosome has two sets of DNA which forms the sister chromatids which are held together at the centromere.

Question

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 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.
