DNA contains many hydrogen bond. Describe a hydrogen bond and explain. How this type of chemical bond holds dna
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.
