This stuff is sad also:
DNA's simple and elegant structure - the "twisted ladder," with sugar-phosphate chains making up the "rails" and oxygen- and nitrogen-containing chemical "rungs" tenuously uniting the two halves - seems to be the work of an accomplished sculptor.
Yet the graceful, sinuous profile of the DNA double helix is the result of random chemical reactions in a simmering, primordial stew. Just how nature arrived at this molecule and its sister molecule, RNA, remains one of the greatest - and potentially unsolvable - scientific mysteries.
