Explanation / Answer

76) Answer = E, Guanine

In nucleotides, nitrogenous bases are the key to the function of DNA. There is rule called complementary base pairing. Cytosine can only bonds with guanine via three hydrogen bonds, and adenine can only bond with thymine via two hydrogen bonds

77) Answer = E, Glucose

Glucose is metabolic fuel molecule and gets converted to lactic acid, which is then utilized as an energy source by brain cells. Glucose is used by intestinal cells and red blood cells.
