WebDNA and proteins are key molecules of the cell nucleus. In 1869, Friedrich Miescher isolated "nuclein," DNA with associated proteins, from cell nuclei. He was the first to identify DNA as a distinct molecule. Phoebus Levene was an organic chemist in the early 1900's. He is perhaps best known for his incorrect tetranucleotide hypothesis of DNA. WebLevene discovered deoxyribose (the D in DNA) in 1929. He also coined the term nucleotide to describe another of his major discoveries: that DNA is made of repeating units of phosphate-sugar-base.
