Hydrogen bond links the two strands in a DNA helix together in the middle.
Who made model of DNA structure?
Watson and Crick made the first model of the DNA molecule based on its X-ray picture, made by Rosalind Franklin. The model explained that the DNA molecule has the shape of helix. It is composed out of two antiparallel strands, interconnected with weak, hydrogen bonds.
Hydrogen bonds occur between the two strands and involve a base from one strand with a base from the second in complementary pairing.
