The Untold History of DNA
How the term "Dexyribose Nucleic Acid" came to be
Observed leucocytes from the pus on fresh surgical bandages (Dahm, 2004).
Noticed a substance precipitated when an acid was added to the solution. He called his substance Nuclein (Dahm, 2004).
Due to the presence inside the nucleus, Miescher called it Nuclein (Dahm, 2004).
FRIEDRICH MIESCHER
I shall call it Nuclein!
1869
Friedrich Miescher
"Nuclein"
1889
Richard Altmann
"Nucleic Acid"
Renamed Nuclein to Nucleic Acid after Albrecht Kossel's discovery that nucleic acids are the bases that make up what is now called DNA (Aliouche, 2019).
Levene discovered DNA found from thymus (now called Thymine) after Kossel's discovery (Frixione & Ruiz-Zamarripa, 2019).
Phoebus Levene
1908
Phoebus Levene
"Thymus Nucleic Acid"
His discovery led to the name change from Thymus Nucleic Acid to Desoxy-Ribose Nucleic Acid (Frixione & Ruiz-Zamarripa, 2019).
1929
Phoebus Levene
"Desoxy-Ribsose Nucleic Acid"
Levene discovered Ribose, the sugar component of DNA that he referred to at the time as d-ribose (Frixione & Ruiz- Zamarripa, 2019).
1953
Watson and Crick
"Deoxyribose Nucleic Acid"
Started using deoxyribose nucleic acid (D.N.A) in their publications on the double helix structure of DNA (Aliouche, 2019).
