Conventional biochemistry had long since told scientists what DNA was made of: four types of organic molecules, known as bases--adenine, cytosine, thymine, guanine, or A, C, T and G--almost certainly strung somehow along a "backbone" of sugar and phosphate. The question was, How? "Perhaps a week of solid fiddling with the molecular models would be necessary," writes Watson, "to make us absolutely sure we had the right answer. Then it would be obvious to the world that Pauling was not the only one capable of true insight...
...must be a helix after all, and on a cold train ride back to Cambridge, Watson decided that two helical sugar-phosphate backbones made more sense than three. "Thus by the time I had cycled back to college and climbed over the back gate, I had decided to build two-chain models. Francis would have to agree. Even though he was a physicist, he knew that important biological objects came in pairs...
Though we all like a good cause, there are some things worth fighting over (such as avoiding war with Iraq), and other things not worth the energy. Valentine’s Day is one of the latter. On the 14th, realizing the sugar-coated materialism that drives the holiday is more important than destroying it.
