Severo Ochoa is best known for being the first to synthesize ribonucleic acid (RNA) outside the cell. He has also discovered several important metabolic processes. For his work with RNA, he received half of the 1959 Nobel Prize in physiology or...

Spanish-born American biochemist Severo Ochoa (1905-1993) spent his life engaged in research into the workings of the human body. In the 1950s, he was one of the first scientists to synthesize the newly discovered ribonucleic acid (RNA) in the...

1905-1993 Spanish-American biochemist who shared the 1959 Nobel Prize with Arthur Kornberg for their discovery of the mechanism of the biological synthesis of ribonucleic acid (RNA). Ochoa's American research career began in the laboratory of...

Severo Ochoa de Albornoz (September 24, 1905 – November 1, 1993) was a Spanish-American biochemist, and the recipient of the 1959 Nobel Prize in Physiology or...

From an early age, Severo Ochoa knew he loved biology and chemistry. But he never intended to practice medicine. He wanted to pursue his passion -- research. There was a problem, though. In his home country, Spain, in the early 1920s, there were no graduate...
