(biochemistry)

DNA

deoxyribonucleic acid; a nucleic acid that is the main constituent of the chromosomes of all organisms (except some viruses). The DNA molecule consists of two polynucleotide chains in the form of a double helix, containing phosphate and the sugar deoxyribose and linked by hydrogen bonds between the complementary bases adenine and thymine or cytosine and guanine. DNA is self-replicating, plays a central role in protein synthesis, and is responsible for the transmission of hereditary characteristics from parents to offspring

On the scientific front, BASF-sponsored research published in the American Journal of Clinical Nutrition demonstrates that a combination of carotenoids (beta-carotene, lycopene and lutein) in dietary supplement form can effectively protect deoxyribonucleic acid (DNA) from oxidative stress damage.
Of course, these analogies also hold a lesson in skepticism: philosophers often talk about carving nature at the joints only to dismiss the idea, and biologists now say that the book of life is not written only in the language of deoxyribonucleic acid, that understanding life requires systems thinking.

In fact, the first sketch of the deoxyribonucleic acid double-helix diagram, made by Francis Crick, is very much an architectural sketch, with soft lines swimming in space, an authoritative representation of geometry, and a confidence in delineation that could easily have come from the hand of Louis Kahn or Eero Saarinen.
