  2. Galacidalacidesoxyribonucleicacid - Wikipedia

    The painting's title is a portmanteau of the name of Dalí's wife, Gala Dalí, and deoxyribonucleic acid (DNA). It is a tribute to Francis Crick and James D. Watson, who are credited with determining the double helical structure of DNA in 1953. The painting is in the collection of the Salvador Dalí Museum in St. Petersburg, Florida. [1]

  3. A-DNA - Wikipedia

    en.wikipedia.org/wiki/A-DNA

    A-DNA is thought to be one of three biologically active double helical structures along with B-DNA and Z-DNA. It is a right-handed double helix fairly similar to the more common B-DNA form, but with a shorter, more compact helical structure whose base pairs are not perpendicular to the helix-axis as

  4. Nucleic acid double helix - Wikipedia

    en.wikipedia.org/wiki/Nucleic_acid_double_helix

    The double-helix model of DNA structure was first published in the journal Nature by James Watson and Francis Crick in 1953, [6] (X,Y,Z coordinates in 1954 [7]) based on the work of Rosalind Franklin and her student Raymond Gosling, who took the crucial X-ray diffraction image of DNA labeled as "Photo 51", [8] [9] and Maurice Wilkins, Alexander Stokes, and Herbert Wilson, [10] and base-pairing ...

    The double helix is the dominant tertiary structure for biological DNA, and is also a possible structure for RNA. Three DNA conformations are believed to be found in nature, A-DNA, B-DNA, and Z-DNA. The "B" form described by James D. Watson and Francis Crick is believed to predominate in cells. [2]

    The wording on the DNA sculpture (donated by James Watson) outside Clare College's Thirkill Court, Cambridge, England is a) on the base: i) "These strands unravel during cell reproduction. Genes are encoded in the sequence of bases." ii) "The double helix model was supported by the work of Rosalind Franklin and Maurice Wilkins." b) on the helices:

    The two strands of DNA in a double helix can thus be pulled apart like a zipper, either by a mechanical force or high temperature. [27] As a result of this base pair complementarity, all the information in the double-stranded sequence of a DNA helix is duplicated on each strand, which is vital in DNA replication.

    DNA replication. The two base-pair complementary chains of the DNA molecule allow replication of the genetic instructions. The "specific pairing" is a key feature of the Watson and Crick model of DNA, the pairing of nucleotide subunits. [5] In DNA, the amount of guanine is equal to cytosine and the amount of adenine is equal to thymine. The A:T ...
