Question
Chapter 43, Problem 1PL
Summary Introduction
Introduction:
Antigens are the substances which are specifically bounded by antibodies. It is a structural molecule that binds specifically to an antibody only in the form of a native antigen. It evokes an immune response either alone or forming a complex with larger molecules and that is capable of binding with a product of the immune response.
Expert Solution & Answer
Answer to Problem 1PL
Correct answer:
The correct answer is option (a) on the red blood cell membranes.
Explanation of Solution
Explanation/justification for the correct answer:
Option (a) on the red blood cell membranes. The blood typing involves the identifying of protein substances called antigens, present on the outer surface of the red blood cell membranes. These include the antigens of the ABO group and those of the Rh group. The ABO blood group antigens are attached to the oligosaccharide chains that project over the surface of red blood cells. These chains are attached to proteins and lipids that lie over the surface of the red blood cell membrane. So, the correct answer is option (b).
Explanation for incorrect answer:
Option (b) within the red blood cell nucleus. The ABO blood group antigens are attached to the oligosaccharide chains that project over the surface of red blood cells and not within the nucleus. Also, the red blood cells are devoid of nucleus. So, this is an incorrect option.
Option (c) within the red blood cell cytosol. The ABO blood group antigens are attached to the oligosaccharide chains that project over the surface of red blood cells and not within the cytosol. So, this is an incorrect answer.
Option (d) on the surface of red blood cell ribosome. The ABO blood group antigens are attached to the oligosaccharide chains that project over the surface of red blood cells. These chains are attached to proteins and lipids that lie over the surface of the red blood cell membrane and not ribosome. So, this is an incorrect answer.
Conclusion
Thus, the antigens related to the ABO blood group are located on the surface of the red blood cell membranes.

If using animals in medical experiments could save human lives, is it ethical to do so? In your answer, apply at least one ethical theory in support of your position.
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.

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.
