Structure of DNA
To form the other side of the â€œtwisted ladderâ€? arrangement of DNA, the bases form weaker hydrogen bonds between each other.
The double-strand, twisted ladder model of DNA structure is more commonly known as the double helix arrangement.
It was discovered in the early 1950s by James Watson and Francis Crick using X-ray diffraction data previously produced by Maurice Wilkins and Rosalind Franklin. Watson, Crick and Wilkins were awarded a Nobel prize for this work in 1962â€Ś
Base Pairings Because of their chemical structure, each base can only join with one other base: Adenine with Thymine A-T Guanine with Cytosine G-C
