The First Discovery of DNA The First Discovery of DNA. Few remember the man who discovered the molecule of life three-quarters of a century before Watson and Crick revealed its structure.Ralf Dahm.ost everybody knows that DNA contains the blueprint for life. The names of Watson and Crick, the first scientists to figure out the structure of DNA in the 1950s, are also widely recognized. But left obscure in history is the name of the chemist who first isolated the DNA molecule itself.

Alexander Fleming Discovers Penicillin However, though they had this knowledge, no one had yet been able to find a chemical that would kill harmful bacteria but also not harm the human body. In 1922, Fleming made an important discovery, lysozyme. While working with some bacteria, Fleming's nose leaked, dropping some mucus onto the dish.

The Discovery of the Electrons  [ edit] The Discovery of the Electrons[edit] The Electron was discovered in 1896, by the British physicist J. J. Thomson, using a cathode rays while doing discharge tube experiments. Thomson also determined e/m, ratio of the charge e to the mass m of the material particle which constituted these rays.

Leaders in Pharmaceutical Business Intelligence (LPBI) Group Chapter 3. In a DNA molecule, the two strands are not parallel, but intertwined with each other. Each strand looks like a helix. The two strands form a  double helix  structure, which was first discovered by James D. Watson and Francis Crick in 1953. In this structure, also known as the B form, the helix makes a turn every 3.4 nm, and the distance between two neighboring base pairs is 0.34 nm.

The Role of Chemistry in History The discovery of ibuprofen was not accidental unlike many other molecules. Its initial purpose was to treat arthritis. It was discovered in the 1950s by Boots Group, a pharmacy chain in the United Kingdom.

- Though Fleming discovered penicillin, it took Florey and Chain to make it a usable product. Though both Fleming and Florey were knighted in 1944 and all three of them (Fleming, Florey and Chain) were awarded the 1945 Nobel Prize in Physiology or Medicine, Fleming is still credited for discovering penicillin.

- Learn More About the Scientists Who Discovered DNA and its Structure written by: Paul Arnold•edited by: Paul Arnold•updated: 9/11/2009 It was Watson and Crick's landmark paper that detailed the double helical structure of DNA, but there is also a long list of inspirational scientists who played key roles in one of the biggest discoveries of the twentieth century. slide 1 of 1. Structure Discovery Frederick Miescher - is the man who discovered DNA. The Swiss physician isolated a high phosphorous-containing substance from white blood cell nuclei in 1869. It was DNA, which he called 'nuclein' because it had come from the nucleus. He did not know its true nature.

Methane In November 1776, methane was first scientifically identified by Italian physicist Alessandro Volta in the marshes of Lake Maggiore straddling Italy and Switzerland. Volta was inspired to search for the substance after reading a paper written by Benjamin Franklin about flammable air.

NEON (REVISED) Chemists have yet to prepare compounds of helium, neon, or argon. Neon was discovered in 1898 by British chemists William Ramsay (1852-1916) and Morris Travers (1872-1961). It occurs naturally in the atmosphere, but only in very small amounts.

Buckminsterfullerene It was first generated in 1985 by Harold Kroto, James R. Heath, Sean O'Brien, Robert Curl, and Richard Smalley at Rice University. Kroto, Curl and Smalley were awarded the 1996 Nobel Prize in Chemistry for their roles in the discovery of buckminsterfullerene and the related class of molecules, the fullerenes.he structure of a buckminsterfullerene is a truncated icosahedron with 60 vertices and 32 faces (20 hexagons and 12 pentagons where no pentagons share a vertex) with a carbon atom at the vertices of each polygon and a bond along each polygon edge.

Fullerene The first fullerene molecule to be discovered, and the family's namesake, buckminsterfullerene (C 60), was prepared in 1985 by Richard Smalley, Robert Curl, James Heath, Sean O'Brien, and Harold Kroto at Rice University.The name was a homage to Buckminster Fuller, whose geodesic domes it resembles.ullerenes are sparingly soluble in many solvents. Common solvents for the fullerenes include aromatics, such as toluene, and others like carbon disulfide. Solutions of pure buckminsterfullerene have a deep purple color.

20 Things You Didnât Know About... DNA 1 Sorry, Jimmy: James Watson and Francis Crick did not discover DNA. That honor goes to Swiss biochemist Friedrich Miescher, who in 1869 found the molecule in the nuclei of white blood cells and called it nuclein. 2 Nor did they figure out that DNA is our genetic blueprint; bacteriologist Oswald Avery and his colleagues did that in the early 1940s. 3 What Watson and Crick did do, in 1953, was decipher the double-helix structure of DNA.

History of Biology: Cell Theory and Cell Structure Early Observations. The invention of the microscope allowed the first view of cells. English physicist and microscopist Robert Hooke (1635–1702) first described cells in 1665. He made thin slices of cork and likened the boxy partitions he observed to the cells (small rooms) in a monastery.he first unequivocal description of the cell nucleus was made by a Czech, Franz Bauer, in 1802 and was given its name in 1831 by Robert Brown (1773–1858) of Scotland, who is best remembered for discovering the random Brownian motion of molecules.

DNA - the carrier of genetic information Johann Friedrich Miescher was the first scientist who proposed the existence of a molecule that carries genetic information. He called it nuclein. But it was only in the 1950s that two young scientists, James Watson and Francis Crick, discovered the true genetic information carriers-molecules of DNA and RNA.uring protein synthesis RNA molecules transfer genetic information from DNA molecules. They also maintain the structure of a cell's ribosomes-protein-making 'factories'. Unlike DNA, RNA can leave the cell's nucleus. See image 3.

WHO DISCOVERED DNA? It was Crick and Watson who worked out the structure of DNA in the 1950's, but its discovery was made nearly 100 years previously by a Swiss physician called Frederick Miescher.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.
