Question

question 2 of 10 which of the following is an important application of hydrogen bonding? a. holding dna together b. mixing of oils c. expanding h₂ gas d. crystallizing nacl

Explanation:

Hydrogen - bonding plays a crucial role in holding the two strands of the DNA double - helix together. The bases in DNA form hydrogen bonds with their complementary bases. Oils are non - polar and do not involve hydrogen bonding for mixing. Expansion of hydrogen gas is related to gas laws and not hydrogen bonding. Crystallization of NaCl is due to ionic bonds, not hydrogen bonds.

Answer:

A. Holding DNA together
