April 26 1928 and English physicist Francis Crick 1916-2004 formally announced they had discovered the secret of life the double helix that forms DNA the molecule containing the genetic instructions for all living organisms. The base pairing of adenine to thymine and of guanine to cytosine was a key piece of information in elucidating the structure of DNA. Read also discovered and chargaff discovered that in dna extracted from organisms Dolly is the first mammal cloned from a non-embryonic cell.
Sixty years ago on April 25 1953 American biologist James Watson b. Chargaff is best known for his discovery of DNA base ratios also known as Chargaffs rules in the late 1940s while working at Columbia University in New York City.

This table lists the base composition of DNA from various organisms.
Chargaff discovered that in DNA extracted from organisms the amounts of guanine and cytosine are roughly the same and the amounts of adenine and thymine are roughly the sameThis discovery is important because the base pairing of adenine to thymine and of guanine to cytosine was a key piece of information in elucidating the structure of DNA. Chargaffs most important contribution to biochemistry was his work with deoxyribonucleic acid more commonly known as DNA. Table below is a representation of Erwin Chargaffs 1952 data. The American biochemist Erwin Chargaff born 1905 discovered that DNA is the primary constituent of the gene thereby helping to create a new approach to the study of the biology of heredity. This molecular diversity added evidence that DNA could be the genetic material. Only the balance of A-T pairs and C-G pairs varies between species.
In 1950 Erwin Chargaff Discovered That The Percentage Of Adenine In Dna Equals The Percentage Of Brainly In 1949 Chargaff discovered that the proportions of bases in DNA depend on the species the DNA comes fromFurthermore what did chargaff discover about the bases of DNA nucleotidesErwin Chargaff found that in DNA the ratios of adenine A to thymine T.
