What Discovery Is Attributed to Phoebus Levene?

The correct answer would be A: identification of ribose and deoxyribose. Phoebus Aaron Theodore Levene is famous for his studies regarding the structure and function of nucleic acids. He categorized different forms of nucleic acids which are DNA (deoxyribonucleic acid) and RNA (ribonucleic acid).

How did Phoebus Levene make his discovery?

Although Levene's studies encompassed nearly every major class of organic compounds, his most valuable work was on the nucleic acids. He isolated the nucleotides, the basic building blocks of the nucleic acid molecule, and in 1909 he isolated the five-carbon sugar d-ribose from the ribonucleic acid (RNA) molecule.

What did Phoebus Levene discover in 1919?

He called this substance a nuclein, but it was later called nucleic acid. Then, 50 years later, in 1919, Russian biochemist Phoebus Levene proposed that nucleic acids were molecules made of phosphate, sugar, and four nitrogenous bases—adenine (A), guanine (G), cytosine (C), and thymine (T).
