Lot 299: Original sketch of a double helix DNA strand on a white 8.5 x 11 sheet, signed in black ballpoint, "James D. Watson, Nobel for DNA 1962." Watson labels the top and bottom of the strand with "Base pair, either A-T or G-C" and "DNA," and adds below, "the average human chromosome has some 100 millions base pairs along its single DNA molecule." In fine condition. Further enhanced by its lack of inscription, this is an exceptional, atypically detailed drawing by the revered geneticist.
