On 25 April 1953 the proposed double helical structure of DNA was first published in Nature and thereafter referred to as the Watson–Crick model, so-named after the two authors. At the time many thought protein was the genetic material and not DNA and there was reluctance among some scientists to accept the model, in part because Watson and Crick had done no experimental work themselves but ...
The discovery of DNA is one of our greatest scientific achievements – these are scientists who led to its discovery. Kath Nightingale. Published: April 10, 2020 at 12:00 am. 1.
Jul 28, 2022 · The background for the work of the four scientists was formed by several scientific breakthroughs: the progress made by X-ray crystallographers in studying organic macromolecules; the growing evidence supplied by geneticists that it was DNA, not protein, in chromosomes that was responsible for heredity; Erwin Chargaff’s experimental finding ...
The discovery of DNA is one of our greatest scientific achievements but how did it happen? Kath Nightingale. Published: April 10, 2020 at 12:00 am. 1869 – Friedrich Miescher discovers DNA in his preparations of white blood cells extracted from the pus in surgical bandages. He calls it ‘nuclein’.
- Eleanor Anne Ormerod (1828-1901), the biographical subject of ‘Miss Ormerod’ by Virginia Woolf, was known internationally. She taught at the Royal Agricultural College, Cirencester and was known for undertaking experiments on herself, including holding a live Crested Newt in her mouth to see how its poison effected humans.
- Beatrix Potter (1866-1943) was more interested in disproving a theory on fungi than she was about Peter Rabbit.
- Caroline Herschel (1750-1848) astronomer, submitted papers to the Royal Society especially on her comet discoveries (she has six comets named after her).
- Dorothy Hodgkin (1910-1994) was state educated and one of only four women to have ever won the Nobel Prize in Chemistry. She lectured at Oxford for most of her career; one of her students was the future Prime Minister Margaret Thatcher, who installed a portrait of Hodgkin in Downing Street in the 1980s.
During the 1970s and 1980s, it helped to produce new and powerful scientific techniques, specifically recombinant DNA research, genetic engineering, rapid gene sequencing, and monoclonal antibodies, techniques on which today's multi-billion dollar biotechnology industry is founded.
