Which discovery is attributed to phoebus levene? extraction and observation of dna2identification of ribose and deoxyribos3e recognition of rna as dna’s messenger construction of an accurate dna model

Answer;

Identification of ribose and deoxyribose

Explanation;

-Phoebus Levene 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.

-Later, he discovered 2-deoxyribose (a sugar derived from D-ribose by removing an oxygen atom), which is part of the deoxyribonucleic acid (DNA) molecule.
