WebDNA is read-only memory, archived safely inside cells. Genetic information is stored in an orderly manner in strands of DNA. DNA is composed of a long linear strand of millions of nucleotides, and is most often found paired with a partner strand. These strands wrap around one another in the familiar double helix, as shown here. WebAug 3, 2015 · The earliest reference that we could find to the "Watson strand" and the "Crick strand" is somewhat tongue-in-cheek and comes from a pair of papers in 1967 by Wacław Szybalski and colleagues. They bound the two DNA strands of phage λ to the synthetic polynucleotide, poly(IG), which has an affinity to cytosine-rich regions.
