4. In the near future, it will soon be possible for people to increase their muscle mass by introducing extra copies of the gene for insulin-like growth factor into their muscle cells.

a. What therapeutic applications can you see for such procedures? [2 marks]

b. It is possible that some people might use this procedure for cosmetic purposes—to gain muscle mass without exercise. Do you think that this would be acceptable, bearing in mind that humans already use cosmetics to change their appearance? [2 marks]

DNA transposons and retrotransposons are similar:

they both have poly-A segments at one end.

both can encode an enzyme required for mobilization.

transposition results in movement of the original transposon to a different place in the genome, losing the previous spot.

during transposition, both go through an RNA form that is copied back into DNA.

Ann O'Rexia suffers from anorexia nervosa. In addition to a low body weight, decreased muscle mass, glycogen, and fat stores, she has iron deficiency anemia. She constantly feels weak and tired. When she walks, she feels pain in her calf muscles. On this visit to her nutritionist, they discuss the vitamin content of her diet and its role in energy metabolism.  She is deficient in thiamine, riboflavin, biotin and niacin (the vitamin precursor of NAD+). In the context of the metabolic pathways discussed in Chapter 14, specifically how would these affect carbohydrate metabolism.

1. One of the symptoms of COVID-19 is a loss of smell or taste.
Identify the type and location of receptors that are likely to be affected by the virus to cause a loss in smell/taste. Explain why people have trouble tasting foods when they are congested due to a cold or allergies.

2. How/why can smells evoke memories so strongly? Identify 1-2 smells that are your most and least favorite and explain why.

Work from the Brown and Goldstein lab provided insights into cholesterol homeostasis that were used to develop several of the LDL cholesterol-lowering therapies, including statins that remain in use today. However, in some patients, statins were not as effective as expected, suggestive of additional mechanisms regulating the LDL receptor. Investigate other LDL cholesterol-lowering therapies (other than PCSK-9 inhibitors), select 1, and compare and contrast the mechanisms of action between the class of drug you select and statins. Include side effects for both types of drugs and information on their efficacy.
