(The Darwin Lectures for 2003, including one by Sir Aaron Klug on Rosalind Franklin's involvement in the determination of the structure of DNA). Robert Olby; The Path to The Double Helix: Discovery of DNA; first published in October 1974 by MacMillan, with foreword by Francis Crick; ISBN 0-486-68117-3; revised in 1994, with a 9-page postscript.
Franklin was a physical chemist who made pivotal research in the discovery of the structure of DNA, known as "the most important discovery" in biology. [1] [2] DNA itself had become "life's most famous molecule". [3] While working at the King's College London in 1951, she discovered two types of DNA called A-DNA and B-DNA. Her X-ray images of ...
1987: Yoshizumi Ishino discovers and describes part of a DNA sequence which later will be called CRISPR. 1989: Thomas Cech discovered that RNA can catalyze chemical reactions, [60] making for one of the most important breakthroughs in molecular genetics, because it elucidates the true function of poorly understood segments of DNA.
In the 1940s and early 1950s, experiments pointed to DNA as the portion of chromosomes (and perhaps other nucleoproteins) that held genes. A focus on new model organisms such as viruses and bacteria, along with the discovery of the double helical structure of DNA in 1953, marked the transition to the era of molecular genetics.
Frederick Sanger OM CH CBE FRS FAA (/ ˈ s æ ŋ ər /; 13 August 1918 – 19 November 2013) was a British biochemist who received the Nobel Prize in Chemistry twice.. He won the 1958 Chemistry Prize for determining the amino acid sequence of insulin and numerous other proteins, demonstrating in the process that each had a unique, definite structure; this was a foundational discovery for the ...

Between 1961 and 1965, the relationship between the information contained in DNA and the structure of proteins was determined: there is a code, the genetic code, which creates a correspondence between the succession of nucleotides in the DNA sequence and a series of amino acids in proteins.
