  2. Galacidalacidesoxyribonucleicacid - Wikipedia

    en.wikipedia.org/wiki/Galacidalacidesoxy...

    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. Obsolete models of DNA structure - Wikipedia

    en.wikipedia.org/wiki/Obsolete_models_of_DNA...

    The DNA double helix was discovered in 1953 [4] (with further details in 1954 [5]) based on X-ray diffraction images of DNA (most notably photo 51, taken by Raymond Gosling and Rosalind Franklin [6]) as well as base-pairing chemical and biochemical information.

  4. Chirality - Wikipedia

    en.wikipedia.org/wiki/Chirality

    An individual who is more dexterous with the right hand is called right-handed, and one who is more skilled with the left is said to be left-handed. Chirality is also seen in the study of facial asymmetry and is known as aurofacial asymmetry. [35] Schema of the development of the axial twist in vertebrates.

    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 ...

    en.wikipedia.org/wiki/Molecular_Structure_of...

    From the DNA double helix model, it was clear that there must be some correspondence between the linear sequences of nucleotides in DNA molecules to the linear sequences of amino acids in proteins. The details of how sequences of DNA instruct cells to make specific proteins was worked out by molecular biologists during the period from 1953 to 1965.

  7. DNA supercoil - Wikipedia

    en.wikipedia.org/wiki/DNA_supercoil

    A negatively supercoiled DNA molecule will produce either a one-start left-handed helix, the toroid, or a two-start right-handed helix with terminal loops, the plectoneme. Plectonemes are typically more common in nature, and this is the shape most bacterial plasmids will take.

  8. DNA unwinding element - Wikipedia

    en.wikipedia.org/wiki/DNA_unwinding_element

    A DNA unwinding element (DUE or DNAUE) is the initiation site for the opening of the double helix structure of the DNA at the origin of replication for DNA synthesis. [1] It is A-T rich and denatures easily due to its low helical stability, [ 2 ] which allows the single-strand region to be recognized by origin recognition complex .

  9. Life Story (film) - Wikipedia

    en.wikipedia.org/wiki/Life_Story_(film)

    The film script was written by William Nicholson, based on James Watson's 1968 memoir The Double Helix: A Personal Account of the Discovery of the Structure of DNA. It was produced and directed by Mick Jackson for Horizon , the long-running British documentary television series on BBC Two that covers science and philosophy.
