Describe the structure of a Dna molecule? Report Abuse. DNA structure DNA structure was first described by James Watson and Francis Crick in 1953. Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions for the development and function of living organisms.All living things contain DNA, with the exception of some viruses with RNA genomes.he nucleotides are joined in such a way that they form a double helix that is like a twisted rope ladder. The steps of the ladder are made by the paired nitrogen bases of opposing nucleotides.

6 Women Scientists Who Were Snubbed Due to Sexism In 1962, Crick was awarded a Nobel Prize for discovering the structure of DNA, along with fellow scientists James Watson and Maurice Wilkins. Several people posted comments about our story that noted one name was missing from the Nobel roster: Rosalind Franklin, a British biophysicist who also studied DNA.ranklin also published in the same issue, providing further details on DNA's structure. Franklin's image of the DNA molecule was key to deciphering its structure, but only Watson, Crick, and Wilkins received the 1962 Nobel Prize in physiology or medicine for their work.

- 1 DNA fingerprinting was invented in 1984 by Professor Sir Alec Jeffreys after he realised you could detect variations in human DNA, in the form of these minisatellites.  DNA fingerprinting is a technique that simultaneously detects lots of minisatellites in the genome to produce a pattern unique to an individual.

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.

- Nucleic Acids 1. Introduction. The first isolation of what we now refer to as DNA was accomplished by Johann Friedrich Miescher circa 1870. He reported finding a weakly acidic substance of unknown function in the nuclei of human white blood cells, and named this material nuclein. A few years later, Miescher separated nuclein into protein and nucleic acid components. In the 1920's nucleic acids were found to be major components of chromosomes, small gene-carrying bodies in the nuclei of complex cells. Elemental analysis of nucleic acids showed the presence of phosphorus, in addition to the usual C, H, N & O.

Atomic nucleus The nucleus was discovered in 1911, as a result of Ernest Rutherford's efforts to test Thomson's plum pudding model of the atom. The electron had already been discovered earlier by J.J. Thomson himself. Knowing that atoms are electrically neutral, Thomson postulated that there must be a positive charge as well.

The First Discovery of DNA The First Discovery of DNA. Most 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.

- Miescher received a chair in 1871 at the University of Basel as professor of physiology. In 1885 he founded Switzerland's first physiological institute at the Vesalianum. He retired in 1895 and died the same year of tuberculosis in Davos. Discovery of nuclein During his stay in the laboratory of Felix Hoppe-Seyler at the University of Tübingen in 1868-69, Miescher was the first to isolate and chemically characterize DNA - from nuclei of leukocytes found in pus from bandages. At that time, the consensus was that cells were largely made of proteins.

Scientists observe single gene activity in living cells in detail for first time Scientists observe single gene activity in living cells in detail for first time Date: May 23, 2011 Source: Albert Einstein College of Medicine Summary: Researchers have for the first time observed the activity of a single gene in living cells. In an unprecedented study, scientists were able to follow, in real time, the process of gene transcription, which occurs when a gene converts its DNA information into molecules of messenger RNA that go on to make the protein coded by the gene.

Concept 15 DNA and proteins are key molecules of the cell nucleus. Concept 15 DNA and proteins are key molecules of the cell nucleus. In 1869, Friedrich Miescher isolated nuclein, DNA with associated proteins, from cell nuclei. He was the first to identify DNA as a distinct molecule. Phoebus Levene was an organic chemist in the early 1900's. He is perhaps best known for his incorrect tetranucleotide hypothesis of DNA.

JUST THE FACTS As Sir Isaac Newton wrote to his rival Robert Hooke, If I have seen further it is by standing on the shoulders of giants.. Crick and Watson's groundbreaking research in working out the structure of DNA was also made possible by 'standing on the shoulders of giants.' One of those was Oswald Avery.owever, all the attention goes to only a few big names such as Crick and Watson. Oswald Avery is one of the unsung heroes of genetics, and it was his work in 1944 that concluded that DNA transmitted hereditary information. slide 1 of 5. There have been many Eureka moments in the history of genetics.

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.
