How Crick and Watson deciphered the DNA

On February 28, 1953,  American molecular biologist James D. Watson and English biophysicist Francis Crick announced to friends that they succeeded to determine the chemical structure of DNA. “When finally interpreted, the genetic messages encoded within our DNA molecules will provide the ultimate answers to the chemical underpinnings of human existence.” – James D. Watson, in [11] DNA and RNA – the Prelude In 1869, the Swiss physician Friedrich Miescher discovered a…

Maurice WIlkins and the Riddle of the DNA Structure

On December 15, 1916, New Zealand-born British physicist, molecular biologist, and Nobel Laureate Maurice Wilkins was born. Wilkins’ research contributed to the scientific understanding of phosphorescence, isotope separation, optical microscopy and X-ray diffraction, and to the development of radar. He is best known for his work at King’s College London on the structure of DNA. Youth and Education Maurice Wilkins was born in Pongaroa, north Wairarapa, New Zealand where his father, Edgar…

Rosalind Franklin and the Beauty of the DNA Structure

Rosalind Franklin (1920–1958) On July 25, 1920, British biophysicist and X-ray crystallographer Rosalind Elsie Franklin was born. She made the first clear X-ray images of DNA’s structure. Her work was described as the most beautiful X-ray photographs ever taken. Franklin’s ‘Photo 51’ informed Crick and Watson of DNA’s double helix structure for which they were awarded a Nobel Prize. Rosalind Franklin was born in Notting Hill, London, as the second of five children into…
