DNA #3: animation of a simplified model of the DNA molecule emphasising the helical structure

DNA or deoxyribonucleic acid stores genetic information in the sequence of base pairs that span the helix like the rungs of a ladder.

The structure of DNA was elucidated over 50 years ago by James Watson and Francis Crick (see 1953 letter in NATURE). For this, they shared a Nobel Prize in 1962 with Maurice Wilkins (who, with Rosalind Franklin, furnished the X-Ray diffraction data).
