The Helical Structure of DNA shows a single strand of DNA. However, as stated earlier, DNA exists as a double-helix, meaning two strands of DNA bind together. Figure %: Double-helical DNA As seen above, one strand is oriented in the 5' to 3' direction while the complementary strand runs in the 3' to 5' direction.
The two DNA strands are held together by interchain hydrogen bonds. H-bonds pair the bases in one chain to the complementary bases in the other chain. (A/T and G/C). Hydrogen Bonds in DNA A number factors are responsible for the stability of the DNA double helix structure, among them hydrogen bonds.
