DNA Timeline

  • Miescher's DNA

    Miescher's DNA
    Miescher removed various phosphate chemicals, which he called nuclein. Nucleic acids are large biomolecules. They are put together of by monomers.
  • Griffith's Experiment

    Griffith's Experiment
    Griffith's Experiment was the first experiment implying that bacteria are able of moving genetic information through a procedure known as transformation.
  • Avery's Experiment

    Avery's Experiment
    Avery undertook dwell of first killing the bacteria with heat and extracting the saline soluble components.
  • Chargaff's Rules

    Chargaff's Rules
    Chargaff's rules states that DNA from any cell of all organisms should have a base Pair Rule of pyrimidine and purine bases and, more specifically, that the amount of guanine is equal to cytosine and the amount of adenine is equal to thymine.
  • Franklin & Wilkin's DNA

    Franklin & Wilkin's DNA
    They both founded the Double Helix. That DNA consists of two chains twisted around each other, or double helixes, of rotating phosphate and sugar groups, and that the two chains are held together by hydrogen bonds between pairs of organic bases.
  • Discovery Of DNA

    Discovery Of DNA
    In the 1900s, many scientists have tried to study deoxyribonucleic acid, which stands for DNA. In the early 1950s two scientists, Rosalind Franklin and Maurice Wilkins, was studying DNA using x-rays.
  • Hershey & Chase's Experiment

    Hershey & Chase's Experiment
    The experiment helped to confirm that DNA is genetic material, which are composed of DNA and protein, infect bacteria, their DNA enters the host bacterial cell, but most of their protein does not.
  • Watson & Crick's Experiment

    Watson & Crick's Experiment
    They discovered the structure of DNA. This was important because now people could understand how it grows and could begin to grow DNA molecules themselves.
