Severo Ochoa de Albornoz (Spanish: [seˈβeɾo oˈtʃoa ðe alβoɾˈnoθ]; 24 September 1905 – 1 November 1993) was a Spanish physician and biochemist, and winner of the 1959 Nobel Prize in Physiology or Medicine together with Arthur Kornberg for their discovery of "the mechanisms in the biological synthesis of deoxyribonucleic acid (DNA)".
It combines a string of words that decodes the meaning of the work. The first word in the string is Gala, Dalí‘s wife and muse. The word ―"cid" refers to a Spanish folklore hero, and Allah is the Arabic word for God. The last word in the string is Dalí's spelling of the full scientific name for DNA—desoxiribunucleicacid."
Deoxyribonucleic acid (/ d iː ˈ ɒ k s ɪ ˌ r aɪ b oʊ nj uː ˌ k l iː ɪ k,-ˌ k l eɪ-/ ⓘ; [1] DNA) is a polymer composed of two polynucleotide chains that coil around each other to form a double helix. The polymer carries genetic instructions for the development, functioning, growth and reproduction of all known organisms and many ...
Although DNA and RNA do not generally occur in the same polynucleotide, the four species of nucleotides may occur in any order in the chain. The sequence of DNA or RNA species for a given polynucleotide is the main factor determining its function in a living organism or a scientific experiment.
Deoxyribonuclease II (DNase II) is also known as acid deoxyribonuclease because it has optimal activity in the low pH environment of lysosomes where it is typically found in higher eukaryotes. Some forms of recombinant DNase II display a high level of activity in low pH in the absence of divalent metal ions, similar to eukaryotic DNase II. [7]
Deoxyribonucleic acid (DNA) is a nucleic acid containing the genetic instructions used in the development and functioning of all known living organisms. The chemical DNA was discovered in 1869, but its role in genetic inheritance was not demonstrated until 1943. The DNA segments that carry this genetic information are called genes.

This nucleotide contains the five-carbon sugar deoxyribose (at center), a nucleobase called adenine (upper right), and one phosphate group (left). The deoxyribose sugar joined only to the nitrogenous base forms a Deoxyribonucleoside called deoxyadenosine, whereas the whole structure along with the phosphate group is a nucleotide, a constituent of DNA with the name deoxyadenosine monophosphate.
