Textbook Question
Chapter 5.1, Problem 1CS
Core Skill: Modeling The goal of this modeling challenge is to propose a model for a transmembrane protein.
Modeling Challenge: As shown in Figure 5.2, some α helices, which are called transmembrane a helices, may be inserted into the hydrophobic region of a membrane and span the entire membrane. Let’s suppose a protein in the plasma membrane has 5 transmembrane α helices. The loops that connect these 5 transmembrane segments are relatively short, except for the one that connects transmembrane segments 4 and 5, which is longer. The amino end projects into the cytosol. Draw a model of this transmembrane protein in the plasma membrane. In your model, draw the transmembrane a helices as cylinders and label them 1 through 5. Also label the amino and carboxyl ends and the cytosol and extracellular environment.

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.

- 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.

The change in Mr due to oxygen binding causes the oxy haemoglobin to have a higher absorbance peak. 4. Oxy-haemoglobin is contaminated by carbaminohemoglobin, and therefore has a higher absorbance peak 5.
