- DNA was first discovered back in 1869 by Johann Friedrich Miescher. The fundamental structure of DNA was discovered by James Watson and Francis Crick, although many people believe that Rosalind Franklin also played a large role in their research.

DNA First isolated by Friedrich Miescher in 1869 and with its molecular structure first identified by James Watson and Francis Crick in 1953, DNA is used by researchers as a molecular tool to explore physical laws and theories, such as the ergodic theorem and the theory of elasticity. gene is a sequence of DNA that contains genetic information and can influence the phenotype of an organism. Within a gene, the sequence of bases along a DNA strand defines a messenger RNA sequence, which then defines one or more protein sequences.

The Discovery of the  Molecular Structure of DNA - The Double Helix 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. He called the compound nuclein..

- The Discovery of DNA's Structure. Taken in 1952, this image is the first X-ray picture of DNA, which led to the discovery of its molecular structure by Watson and Crick. Created by Rosalind Franklin using a technique called X-ray crystallography, it revealed the helical shape of the DNA molecule.atson and Crick realized that DNA was made up of two chains of nucleotide pairs that encode the genetic information for all living things.

February 28: The Day Scientists Discovered the Double Helix Indeed, they had. That very morning, the two men worked out the double helix structure of deoxyribonucleic acid, better known to every first-grader as DNA. Mind you, they did not discover DNA. That scientific feat was actually accomplished in 1869 by Friedrich Miescher, a physiological chemist working in Basel, Switzerland. Miescher determined that DNA, a nucleic acid found in the cell's nucleus, was comprised of sugar, phosphoric acid, and several nitrogen containing bases.

How Did the Discovery of DNA Impact the Scientific Community? Identification of DNA. DNA's discovery can be traced to 1868, when Swiss medical student Johann Friedrich Miescher began work on isolating proteins from white blood cells. Miescher found a substance that contained more phosphorus than cellular proteins and could not be broken down as proteins could. His discovery of what he called “nuclein” proved an important key for scientists decades later who were trying to determine which chemical components of cells carried genetic information.

What was Friedrich Miescher's contribution to the discovery of the genetic code? Friedrich (Fritz) Miescher's discovered DNA in the cell nucleus Fritz Miescher was a Swiss physician. He reported discovering the DNA molecule in the cell's nucleus in 1868. This created speculation that the DNA might have something to do with genetics.

- What DNA is Made of. A DNA molecule contains all the information necessary to grow, build and maintain an organism. First discovered in 1869 by Frederick Miescher, it's fundamental to our understanding of basic genetics.eoxyribose-This is a sugar, known chemically as a pentose, a five-carbon sugar. Nucleic-Refers to the location of DNA inside the nucleus. The molecule was originally called 'nuclein' by Frederick Miescher, the man who discovered DNA in 1869.
