WHO DISCOVERED DNA? The man who discovered DNA, Frederick Miescher, was a young physician who worked in the laboratory of physiological chemistry of eminent scientist Felix Hoppe-Seyler. At the time of the discovery he was in his 25th year and had not long graduated from his studies.iescher discovered DNA in 1869 whilst studying pus-ridden bandages that were being sent to the laboratory by the local clinic. At this time the lab was working on the chemistry of body fluids, particularly blood. To that end the young physician was studying lymphocytes, though these were hard to obtain.

The Discovery of the  Molecular Structure of DNA - The Double Helix The work of many scientists paved the way for the exploration of DNA. Way back in 1868, almost a century before the Nobel Prize was awarded to Watson, Crick and Wilkins, a young Swiss physician named Friedrich Miescher, isolated something no one had ever seen before from the nuclei of cells.

- James Watson and Francis Crick explain how they solved the structure of DNA. I'm James Watson. I'm Francis Crick. In 1953, Francis and I published the first accurate model of the DNA molecule. We were interested in DNA — the hereditary molecule of life. We wanted to build on what was chemically known about DNA, and determine its actual structure.

Watson and Crick discover chemical structure of DNA Though DNA–short for deoxyribonucleic acid–was discovered in 1869, its crucial role in determining genetic inheritance wasn’t demonstrated until 1943. In the early 1950s, Watson and Crick were only two of many scientists working on figuring out the structure of DNA. California chemist Linus Pauling suggested an incorrect model at the beginning of 1953, prompting Watson and Crick to try and beat Pauling at his own game.

- 3. Protect it. When it's time to leave the house, protect your blister to prevent it from popping and becoming infected. Use a donut moleskin bandage to cover it. 1  If the blister is on your foot, wear socks and comfortable shoes-don't make it worse by walking around in the shoes that caused the blister to begin with.. Bandage the area. Use a Band-aid (plaster) or gauze to loosely bandage the area, so it still gets a little air flow. Make sure the tape doesn't touch the deflated blister. 1  Change the bandage once a day, or every time it gets wet or dirty. 2  Check the area when you change the bandage.

The Unsung Hero Who Discovered The Double Helix It's commonly believed that James Watson and Francis Crick discovered the double helix shape of DNA. But in fact, they based their work on one of their colleagues at King's College in London - Rosalind Franklin, an x-ray diffraction expert whose images of DNA proteins in the early 1950s revealed a helix shape.
