Instead, many scientists uncovered more and more about DNA from 1869-1953, until it culminated in the discovery of the famous double helix. That's why it was named nucleic acid, a name DNA still has today. No one person discovered DNA. 07/06/2016It’s 30 years since DNA fingerprinting was first used in a police investigation.

By Rebecca Skloot.
In 1953 scientists James Watson, Francis Crick, Maurice Wilkins, and Rosalind Franklin determined the double-helix structure of DNA, as well as its method of replication. January 14, 2003. 11/10/2013James Watson was a pioneer molecular biologist who, along with two other scientists, was awarded the Nobel Prize for discovering the double helix structure of the DNA molecule. Chargaff, Watson and Crick, and Wilkins and Franklin.
At King’s College London, Rosalind Franklin obtained images of DNA using X-ray crystallography, an idea first broached by Maurice Wilkins.
Instead, many scientists uncovered more and more about DNA from 1869-1953, until it culminated in the discovery of the famous double helix. Who Discovered DNA? The sentence "This structure has novel features which are of considerable biological interest" may be one of science's most famous understatements.
In 1962 Watson (b.

Chargaff, Watson and Crick, and Wilkins and Franklin. Franklin’s images allowed James Watson and Francis Crick to create their famous two-strand, or double-helix, model. The discovery of the molecular structure of DNA - the double helix A scientific breakthrough. The structure of DNA double helix and how it was discovered. It all started humbly enough in 1869, when Swiss chemist Johann Friedrich Miescher found a phosphorus-containing substance much different from the proteins …
He determined that the nuclein was rich in phosphorous and was also acidic.

Science in Seconds (www.scienceinseconds.com) DNA was first discovered in 1869, but its role in genetics was not clear until the 1940s. It all started humbly enough in 1869, when Swiss chemist Johann Friedrich Miescher found a phosphorus-containing substance very different from the proteins he was looking for in white blood cells. The structure of DNA double helix and how it was discovered. No one person discovered DNA.
Who Discovered DNA? DNA was discovered by a Swiss medical student named Johann Friedrich Miescher, who found it when working with white blood cells that he took from pus drained out of a surgical wound. The technique has since put millions of criminals behind bars – …
