Genetics Timeline

  • Watson and Crick discover the shape and makeup of DNA

    Watson and Crick discover the shape and makeup of DNA
    Watson and Crick are two college graduates who were studying the makeup and shape of DNA. With the help of Rosalind Franklin's photos, The two of them figured out the double helix shape of DNA with their models by figuring out the A,T,G,C connections. (JAN 1 is NOT the correct date)
  • Period: to

    Watson & Crick to Human Genome Project

  • 46 Human Chromosomes

    46 Human Chromosomes
    Joe Hin Tjio discovered that 46 chromosomes is the exact number of cells in a human cell.
  • DNA copying enzyme

    DNA copying enzyme
    Arthur Kornberg and his helpers isolated a DNA enzyme that would soon be used for DNA sequencing.
  • mRNA Carries Info

    mRNA Carries Info
    Sydney Brenner, François Jacob and Matthew Meselson
    discover that mRNA takes information from DNA in the
    nucleus to the cytoplasm.
  • First Animal Gene Cloned

    First Animal Gene Cloned
    Researchers copied frog DNA and were successful.
  • First Transgenic Mice and Fruit Flies

    First Transgenic Mice and Fruit Flies
    Scientists successfully add stably inherited genes to laboratory
    animals. This tested the functions of genes.
  • Launch of the Human Genome Project

    Launch of the Human Genome Project
    The Department of Energy and the National Institutes of
    Health announce a plan for a 15-year project to sequence the
    human genome.
  • Mouse Genetic Map Completed

    Mouse Genetic Map Completed
    The lab mouse is valuable for genetics research because
    humans and mice share almost all of their genes, and the
    genes on average are 85% identical.
  • Completion of the Human Genome Sequencing

    Completion of the Human Genome Sequencing
    The finished human genome sequence will be at least 99.99%
    accurate.
