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.

Why were James Watson and francis crick given the credit for the discovery of DNA structure?
They were famous for discovering the structure of DNA. The discovery of DNA did not come about by chance or luck. Crick and Watson, like all good scientists kept their eyes open, asked questions and made sure that nothing that could be potentially informative was allowed to slip by.

James Watson and Francis Crick. With good data support from Rosalind Franklin and Maurice Wilkins.
