Answer:
The correct answer is option b. "Malnutrition has no significant effect on the genomic base pair content of a person's muscles".
Explanation:
Chargaff's Rules state that the content of nucleotides in the cells have a 1:1 ratio of pyrimidine and purine bases and the composition of DNA varies from one species to another but not within the same specie. Therefore according to Chargaff's Rules malnutrition has no significant effect on the genomic base pair content of a person's muscles, since no variation of the genomic base pair content should occur within the same person or specie.

Answer
b. Regulate the diet of the affected persons to severely limit the uptake of the amino acid.
Explanation:
<u>This is the effective way of managing PKU, if diet is not regulated, the blood plasma Phenylketonuria levels continue to build up from usual protein consumption. This leads to toxicity of the brain and brain dysfunctions. Nausea constipation, fatigues, health headaches are some of the results of the build up</u>.
Therefore to reduce the blood build up of phenylalanine and thus PKU; Special diet formulas rich in essential amino acids, and other needed nutrients which may be absent in phenylalanine low diet should be adopted. Amino acids substitutes notably Tyrosine which is lacking from failure of phenyalanine breakdown in phenylketouria is heavily supplemented. Tyrosine is important in brain function for alertness, focus,nervous communication.
The adoption of protein substitutes diet or regulated amino acid diet is very important because , all the needed amino acid are available , thus protein catabolisms which may trigger phenylalanine build up from muscles and liver storage withdrawal is prevented thus stabilizing its blood concentration.

Answer:
E. Interleukin-1
Explanation:
Interleukin-1 is produced by macrophages and is involved in promoting the proliferation of helper T cells. Interleukin-1 also acts on the hypothalamus to cause fever. Fever refers to abnormally high body temperature. During infection and inflammation, the hypothalamic thermostat is reset in response to interleukin-1 resulting in fever. The presence of certain bacterial toxins in the body triggers the release of interleukin-1 from macrophages and the body temperature is elevated. Fever inhibits the growth of some microbes, intensifies the effects of interferons, and stimulates the body's immune reactions.
