Summary Introduction

Introduction:

The electrocardiogram (ECG) is a process through which the electrical activity of the heart is recorded on a characteristic graph paper. The heart is myogenic, that means it consists of specific cardiac muscles that can generate electrical impulses on their own. The sinoatrial nodes are the pacemakers of the heart. The ECG records the electrical activity of the heart on a graphical paper where different tracings are present. The tracings correspond to the systole, diastole and other processes in the heart. The graphical representation has a characteristic amplitude, direction, and duration of the different tracings. The standard ECG uses a 12-lead system, which are the electrodes.

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.
