  • DNA Mystery Solved 50 Years Ago
    • DNA (Acronym for deoxyribonucleic acid. It is used to encode genetic information.)
    • Watson and Crick developed the double-helix model for DNA 50 years ago, based on X-ray diffraction data taken by Maurice Wilkins.
      • On 28 February, 1953, Francis Crick walked into the Eagle Pub in Cambridge, UK and announced the discover
      • Later he and Watson would share the Nobel Prize
    • DNA Encodes information in a biological computer program in base 4
      • The nucleotides are composed of a sugar (ribose), phosphate, and one of 4 nitrogenous bases: adenine (A), cytosine (C), guanine (G), or thymine (T). The sequence of these bases is used to encode the genetic information for building protein.
      • Selected sequence file sizes are shown below.
