Answer #1

The complementary base pairs of DNA, guanine with cytosine and adenine with thymine are bound to one another by hydrogen bonds. The hydrogen bonds keeps the two strands of a DNA helix together because of their strong dipole-dipole attraction. The thymine-adenine pair is bound by two hydrogen bonds. The cytosine-guanine pair is bound by three hydrogen bonds. Higher G-C content in a DNA results in higher melting temperatures due to the triple hydrogen bonds between their bases.

Hydrogen gas is a very useful reagent with many uses in the petroleum, food, and chemical industries. Most hydrogen exists in covalently bonded molecules, and atmospheric air contains less than 1 ppm of diatomic hydrogen. Therefore, hydrogen gas is produced on a large scale for these uses, where steam reforming with methane and electrolysis of water are two of the primary methods. The more economic reaction of steam reforming is the reverse of the reaction depicted in Carbon Monoxide and...
