A major milestone in molecular biology was the discovery of the structure of DNA. This work began in 1869 by Friedrich Miescher , a Swiss biochemist who first proposed a structure called nuclein , which we now know to be (deoxyribonucleic acid), or DNA. [ 15 ]
The development of molecular biology was not just the fruit of some sort of intrinsic "necessity" in the history of ideas, but was a characteristically historical phenomenon, with all of its unknowns, imponderables and contingencies: the remarkable developments in physics at the beginning of the 20th century highlighted the relative lateness in ...

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. 1989: The human gene that encodes the CFTR protein was sequenced by Francis Collins and Lap-Chee Tsui.
The history of biology traces the study of the living world from ancient to modern times. Although the concept of biology as a single coherent field arose in the 19th century, the biological sciences emerged from traditions of medicine and natural history reaching back to Ayurveda, ancient Egyptian medicine and the works of Aristotle, Theophrastus and Galen in the ancient Greco-Roman world.
1953: James Watson, Francis Crick, Maurice Wilkins and Rosalind Franklin: helical structure of DNA, basis for molecular biology; 1957: Chien Shiung Wu: demonstrated that parity, and thus charge conjugation and time-reversals, are violated for weak interactions; 1962: Riccardo Giacconi and his team discover the first cosmic x-ray source ...
The events include Oysterfest on June 15 to NB Roots & Branches on July 20, as well as the always fun Whaling City Festival July 11-14 and the 108th annual Celebration of the Feast of the Blessed ...
