- Genes Control Biochemical Events (1930)
- Some Genes Can Jump (1940)
- DNA Is the Genetic Material (1928, 1944, 1952)

What are genetic discoveries?
Gene discovery involves the identification of differentially expressed genes between two or more states, for example disease and normal tissue. The goal of gene discovery is to elucidate novel genetic pathways or cause-specific therapies.
What has been discovered about DNA recently?
The discovery of what’s described as a ‘twisted knot’ of DNA in living cells confirms our complex genetic code is crafted with more intricate symmetry than just the double helix structure everybody associates with DNA. Importantly, the forms these molecular variants take affect how our biology functions.
What was the first gene discovered?
In 1972, Walter Fiers and his team at the University of Ghent were the first to determine the sequence of a gene: the gene for bacteriophage MS2 coat protein.
Why was the discovery of genetics so significant?
The discovery in 1953 of the double helix, the twisted-ladder structure of deoxyribonucleic acid (DNA), by James Watson and Francis Crick marked a milestone in the history of science and gave rise to modern molecular biology, which is largely concerned with understanding how genes control the chemical processes within …
Who first discovered genetics?
Gregor Mendel
In the 19th century, it was commonly believed that an organism’s traits were passed on to offspring in a blend of characteristics ‘donated’ by each parent.
When did Rosalind discover DNA?
On 6 May 1952, at King´s College London in London, England, Rosalind Franklin photographed her fifty-first X-ray diffraction pattern of deoxyribosenucleic acid, or DNA.

Does triple helix DNA exist?
Based on the way a double-stranded DNA helix is formed, a triple-stranded helix would not be possible.
What did Rosalind Franklin discover?
the double helix structure of DNA
Rosalind Franklin made a crucial contribution to the discovery of the double helix structure of DNA, but some would say she got a raw deal. Biographer Brenda Maddox called her the “Dark Lady of DNA,” based on a once disparaging reference to Franklin by one of her coworkers.
