Chapter 19.2, Problem 5CC
Summary Introduction
To propose a hypothesis: To identify ways to block the molecular pathway to fight HIV infection.
Concept introduction: HIV is a retrovirus having RNA as a genetic material. HIV mainly attacks the immune cells, especially CD4 cells. CD4 cells play an essential role by protecting the body from any infection. Antiretroviral therapy is a method of suppressing or preventing HIV infection using drugs, e.g., Tenofovir, Zidovudine.

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.
Design a grafting experiment to determine if limb mesoderm determines forelimb / hindlimb identity. Include the experiment, a control, and an interpretation in your answer.
The Snapdragon is a popular garden flower that comes in a variety of colours, including red, yellow, and orange. The genotypes and associated phenotypes for some of these flowers are as follows:
aabb: yellow
AABB, AABb, AaBb, and AaBB: red
AAbb and Aabb: orange
aaBB: yellow
aaBb: ?
Based on this information, what would the phenotype of a Snapdragon with the genotype aaBb be and why?
Question 21 options:
orange because A is epistatic to B
yellow because A is epistatic to B
red because B is epistatic to A
orange because B is epistatic to A
red because A is epistatic to B
yellow because B is epistatic to A

- A sample of blood was taken from the above individual and prepared for haemoglobin analysis. However, when water was added the cells did not lyse and looked normal in size and shape. The technician suspected that they had may have made an error in the protocol – what is the most likely explanation? The cell membranes are more resistant than normal. An isotonic solution had been added instead of water. A solution of 0.1 M NaCl had been added instead of water. Not enough water had been added to the red blood cell pellet. The man had sickle-cell anaemia.arrow_forwardA sample of blood was taken from the above individual and prepared for haemoglobin analysis.

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.
