1. a single-based DNA gene coding changes that is LEAST LIKELY to significantly affect the function of
Silent mutations in the 3RD CODON BASE
2. a property of the enhancer element?
They could work when located long distances from the promoter
3. ______ is considered as a transcriptional regulation control?
Chromatin remodelling
4. TRUE of biological membrane structure
Cholesterol is an amphipathic molecule
5. Defines the specificity of hormone activity in a cell
The presence of the hormone receptor
6. TRUE of hormones
lipophilic hormones need transport proteins
7. a vitamin that is essential for one-carbon metabolism
Folic Acid (vit B9)
8. Which statement is true about competitive inhibition?
Usually the inhibitor structurally resembles the normal substrate
9. The active form of Vitamin B12 coenzyme:
5-deoxyadenosylcobalamin
10. TRUE statement regarding carbohydrate digestion
It initially takes place in the mouth through the action of AMYLASE
11. In man, glucose from dietary cellulose could not be available for energy because:
man inherently lacks the enzyme to hydrolyze cellulose
12. A 3 month old infant develops diarrhea and abdominal discomfort following a milk formula. however,
history revealed that he was able to tolerate breast feedings and the same milk formula at birth. The most
secondary lactose intolerance
13. Hexokinase differs from glucokinase by
hexokinase being inhibited by glucose 6 phosphate
