Gregor Mendel, the pioneer of contemporary
genetics, elucidates his investigations on
experiments in plant hybridization.
(1866-1945)
Thomas Hunt Morgan
He discovered the relationship between genes
and chromosomes, using the fruit fly as a
model organism.
(1920-1958)
Rosalind Franklin
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.
(1928-) and (1916-2004)
James Watson y Francis Crick
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.
(1902-1992)
Barbara McClintock
She discovered mobile elements or "jumping genes" in
maize, demonstrating that genes can change position
in chromosomes.
(1910-1976) and (1920-2013)
Jacques Monod (1910-1976) y François Jacob
They proposed the model of gene regulation in E. coli bacteria,
known as the "operon".
(1927-2019)
Sydney Brenner
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.
(1946-)
Mary-Claire King
She discovered the BRCA1 gene, which is involved in
hereditary breast and ovarian cancer.
(1903-1989) and (1909-1975)
George Beadle y Edward Tatum
They proposed the one-gene-one-enzyme theory, showing that
a gene codes for a specific enzyme.
(1909-2012)
Rita Levi-Montalcini
She discovered nerve growth factor (NGF), laying the foundation for
understanding neural development and winning the Nobel Prize in
Physiology or Medicine in 1986.
