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 made his initial proposal in 1919, discrediting other suggestions that had been put forth about the structure of nucleic acids. In Levene's own words, "New facts and new evidence may cause its alteration, but there is no doubt as to the polynucleotide structure of the yeast nucleic acid" (1919).
WebPhoebus Levene believed that the four nucleotides in DNA are not linked or repeated in the same pattern and that they are held together by phosphodiester bonds. He discovered that the nucleotides were held together by phosphodiester bonds, in which two phosphate groups bind two sugars together. 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.
