Francis Crick, James D. Watson, and Rosalind Franklin discover the molecular structure of DNA.
Date: 1953
Crick and Watson draw heavily on the work of another DNA researcher, Rosalind Franklin, who is not included in the announcement and does not receive a Nobel Prize alongside the male researchers.
Immediately after the structure is published, several researchers begin to patent nucleotide derivatives, some of which naturally occur. This is an early precursor to genetic patenting.
Crick and Watson present: "a double helix that contained two long, helical strands wound together" (Hernandez, 2020), and this begins the onset of scientific researchers attempting to produce synthetic DNA.
