DNA Discovery: Selected Events
1865 - Mendel's Laws of Heredity presented.
1868 - Miescher isolated "Nuclein",
a compound that includes nucleic acid, from pus cells isolated.
1905-1908 - Bateson and Punnett showed
that genes modify action of other genes.

of inheritance.

and RNA are always present in cells.

function.

from one chromosome position to another.
1953 - Watson and Crick proposed double-stranded,
helical, complementary, anti-parallel model for DNA.
1966 - Nirenberg, Mathaei, and Ochoa demonstrated
that sequence of three nucleotide bases (a codon) determines each
of 20 amino acids.
1973 - First human-gene mapping conference
held.
1990 - Human Genome Project launched.
