HUMAMAN GENOME TIMELINE
  1. (1822-1884)
    1. Gerorge Mendel
      1. Gregor Mendel, the pioneer of contemporary genetics, elucidates his investigations on experiments in plant hybridization.
    2. (1866-1945)
      1. Thomas Hunt Morgan
        1. He discovered the relationship between genes and chromosomes, using the fruit fly as a model organism.
      2. (1920-1958)
        1. Rosalind Franklin
          1. She contributed to the discovery of the structure of DNA through her work with X-ray diffraction imaging, although she was not initially recognised for it.
        2. (1928-) and (1916-2004)
          1. James Watson y Francis Crick
            1. Together they proposed the model of the double helix structure of DNA in 1953, based on the work of other scientists, including Franklin's X-ray diffraction photography.
          2. (1902-1992)
            1. Barbara McClintock
              1. She discovered mobile elements or "jumping genes" in maize, demonstrating that genes can change position in chromosomes.
            2. (1910-1976) and (1920-2013)
              1. Jacques Monod (1910-1976) y François Jacob
                1. They proposed the model of gene regulation in E. coli bacteria, known as the "operon".
              2. (1927-2019)
                1. Sydney Brenner
                  1. She made important contributions to the understanding of the genetic code and the organisation of the nervous system through her work with the worm Caenorhabditis elegans.
                2. (1946-)
                  1. Mary-Claire King
                    1. She discovered the BRCA1 gene, which is involved in hereditary breast and ovarian cancer.
                  2. (1903-1989) and (1909-1975)
                    1. George Beadle y Edward Tatum
                      1. They proposed the one-gene-one-enzyme theory, showing that a gene codes for a specific enzyme.
                    2. (1909-2012)
                      1. Rita Levi-Montalcini
                        1. She discovered nerve growth factor (NGF), laying the foundation for understanding neural development and winning the Nobel Prize in Physiology or Medicine in 1986.
