Chapter 4, Problem 5A
Summary Introduction
Introduction:
The smooth muscles are elongated cells with a spindle shape. They are uninucleate with a single nucleus. They do not have any markings or striations. They have an involuntary action. There are located on the walls of blood cells containing endothelial cells and on the lining of digestive tract in humans. The skeletal muscles have marking with striations of fibers. They are voluntary muscles which respond to stimuli. They have cells with many nuclei. The fibers are made of actin and myosin filaments. The cardiac muscles have markings and striations which contract to help in the flow of blood from the heart to the various organs. There are various intercalated disc present in the cardiac muscle fibers.

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.

- Which ONE of the following is FALSE regarding haemoglobin? It has two alpha subunits and two beta subunits. The subunits are joined by disulphide bonds. Each subunit covalently binds a haem group. Conformational change in one subunit can be transmitted to another. There are many variant ("mutant") forms of haemoglobin that are not harmful.arrow_forwardWhich ONE of the following is FALSE regarding haemoglobin? It has two alpha subunits and two beta subunits.
