Question
Chapter 7, Problem 12bCP
Summary Introduction
To review:
The following:
1. The process of inactivation of monoamines at the synapse.
2. Clinical manipulation of this process
Introduction:
Monoamines are a class of regulatory molecules that are derived from various amino acids. Some monoamines like dopamine, norepinephrine and epinephrine are obtained or derived from tyrosine, which is also an amino acid. Similar to ACh (acetylcholine), monoamine neurotransmitters are also released by the process of exocytosis which get diffused across the synaptic cleft to reach the postsynaptic cell membrane.

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.
