In 1869, the physician Friedrich Miescher first isolated DNA. While examining the substance ofpus in surgical bandages, he observed a microscopic substance in the pus. He named it nuclein because he observed it in the nuclei of cells.
Then, in 1919, Phoebus Levene realized that this "nuclein" was composed of a base, a sugar, and a phosphate nucleotide unit. Attempting to discern the structure of the DNA, Levene proposed that it was structured out of a string of nucleotides units that were linked together.
He suggested that they were linked together through the phosphate groups. This conjecture was wrong however, because Levene's suggested a short chain. He further suggested that the bases repeated in a fixed order, which was incorrect.
