Question
Nutrients can be used to compensate for some gaps in our DNA. For example:a. Individuals with a change in the base sequence for the phenylalanine hydroxylase gene can correct the sequence of bases by eating a lot of phenylalanine.
b. Obese individuals can lose body weight by eating fewer calories than they expend.
c. Omega-3 fatty acids can up-regulate genes encoding for fat oxidation.
d. Individuals with a polymorphism that decreases activity of a folate-metabolizing enzyme, methylene tetrahydrofolate reductase, may have more elevated plasma homocysteine than those with a normal enzyme while more folate intake can normalize plasma homocysteine for those with this polymorphism.
