Dna held together by hydrogen bond
WebA DNA molecule consists of two polynucleotide strands that form a double helix. The strands are held together by hydrogen bonds between the nitrogen‑containing bases. One strand is complementary to the other strand, which means that a base on one strand is … WebHowever, weaker hydrogen bonds hold together the two strands of the DNA double helix. These weak bonds keep the DNA stable, but also allow it to be opened up for copying and use by the cell. More generally, …
