1866- Gregor Johann Mendel, an Austrian botanist and monk, outlines the
basics of heredicty by breeding pea plants.
1910- Working with fruit flies, Thomas Hunt Morgan fiinds Genes
are organized along chromosomes; 30 years later scientists propose genes are
made of DNA.
1953- Biologists James Watson and Francis Crick discover the helical
structure of DNA. They win the Nobel Prize.
1984- Leroy E. Hood of the California Institute of Technology begins work to
create the first reliable prototype of the DNA sequencer. Two years later,
PE Biosystems introduces the first automated sequencer.
1987- The first human disease gene, muscular dystrophy, is found. Genes for
cystic fibrosis, Huntington's disease and breast cancer are found.
1989- The National Center for Human Genome Research is created to oversea
the $3 billion public effort to map all human DNA by 2005.
1995- J. Craig Venter completes the first full sequence of a living
organism, a bacterium that causes meningitis.
1999- A high-speed sequencer completes an entire human chromosome, and the
race to map the human genome kicks into high gear.
