What did chargaff discover and why was this important?
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. Chargaff’s most important contribution to biochemistry was his work with deoxyribonucleic acid, more commonly known as DNA.
What did Erwin Chargaff Discover and when?
The American biochemist Erwin Chargaff (1905-2002) 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. Erwin Chargaff was born in Austria on August 11, 1905.
When did chargaff discover?
In 1950, he discovered that the amounts of adenine and thymine in DNA were roughly the same, as were the amounts of cytosine and guanine. This later became known as the first of Chargaff’s rules.
What organisms did chargaff study?
Yale. Between 1928 and 1930, Chargaff worked successfully with Yale’s Rudolph Anderson, publishing seven papers, discovering two branched-chain fatty acids, and studying the tuberculosis bacterium. Unfortunately, he and his Austrian wife grew homesick – life in America was depressing.
When did Watson and Crick discover DNA?
1953
The discovery in 1953 of the double helix, the twisted-ladder structure of deoxyribonucleic acid (DNA), by James Watson and Francis Crick marked a milestone in the history of science and gave rise to modern molecular biology, which is largely concerned with understanding how genes control the chemical processes within …
What did Franklin discover about the structure of DNA?
Rosalind Franklin discovered the density of DNA and, more importantly, established that the molecule existed in a helical conformation. Her work to make clearer X-ray patterns of DNA molecules laid the foundation for James Watson and Francis Crick’s suggestion that DNA is a double-helix polymer in 1953.
