Work
In 1944, Oswald Avery proved that DNA is the bearer of organisms' genetic code. Further explanation was provided when James Watson and Francis Crick determined the structure of the DNA molecule in 1953. This structure–a long double helix–contains a long row of pairs of four different nitrogen bases, which allow the molecule to function like a code. The molecule's structure also explains how it is able to copy itself. The nitrogen bases always pair in the same constellations, so that if a molecule is split, its halves can be supplemented so that they form copies of the original molecule.
Nobel Prizes and laureates
Six prizes were awarded for achievements that have conferred the greatest benefit to humankind. The 12 laureates' work and discoveries range from proteins' structures and machine learning to fighting for a world free of nuclear weapons.
