Molecular Biology of the Gene - James D. Watson - Google книгиOn April 25th, , James Watson and Francis Crick of the Cavendish Laboratory, at Cambridge University, published their proposal of the double helix, a model of the structure of DNA, the chemical of which genes are made. Their discovery ranks with that of natural selection by Darwin and Wallace as the most important in biology. The model showed how the sequence of four chemical units, the bases, arranged in a long but simple, polymeric molecule of DNA, could accommodate the great diversity of genetic information. The bases are the letters of the genetic language. They are arranged in two helical strands as a sequence of so-called base pairs. The model suggested how the sequence might replicate and mutate.

One of the greatest nonfiction books, his memoir provides candid insights into one of the most momentous discoveries of the 20th century, also revealing the scientific quest for the truth as being subjective and messy, a knotty combination of both the collegiate and competitive. The title refers to their momentous discovery in of the structure of the molecule in our cells that forms our genes, a twisting pair of strands of deoxyribonucleic acid DNA that has been unravelling to replicate itself since the dawn of life some four billion years ago. They had ushered in a new era of molecular biology, with an insight that was profound. We gathered in the smart six-storey brownstone home of author Andrew Solomon, where the CSHL archivist Mila Pollock showed us the first editions of the book, along with extracts that appeared in The Atlantic. I asked him — had the prize had emboldened him to be candid? Watson describes how they raced to beat their great American rival, Linus Pauling.
Other scientists, like Rosalind Franklin and Maurice Wilkins , also contributed to this discovery. James Dewey Watson was born in Chicago. As a child, he was bright and inquisitive. One of his favorite words was "why? He used this money to buy binoculars for bird-watching?
Watson and Crick deciphered the structure of DNA around 60 years ago and thus provided the key to understanding how genetic information is passed on. Since this discovery, which laid the foundation for molecular biology, new insights and developments have significantly changed many research areas and have also found their way into our everyday lives. In simple terms, deoxyribonucleic acid DNA is the stuff that genes are made of. The highly specialised biomolecule is impressive with its simple but powerful structure that winds around itself and which was discovered by James Watson and Francis Crick in The scientists were later awarded the Nobel Prize in Physiology or Medicine.

Then, in the decades following Miescher's discovery, other scientists--notably, Phoebus Levene and Erwin Chargaff--carried out a series of research efforts that revealed additional details about the DNA molecule, including its primary chemical components and the ways in which they joined with one another. Without the scientific foundation provided by these pioneers, Watson and Crick may never have reached their groundbreaking conclusion of that the DNA molecule exists in the form of a three-dimensional double helix. Although few people realize it, was a landmark year in genetic research, because it was the year in which Swiss physiological chemist Friedrich Miescher first identified what he called "nuclein" inside the nuclei of human white blood cells.
James Dewey Watson James D. Watson was born on April 6, Watson was an extremely industrious student and entered the University of Chicago when he was only He received his Bachelor of Science degree in Zoology four years later, and went on to earn a Ph. He was performing research at the University of Copenhagen in Denmark, when he first learned of the biomolecular research at the Cavendish Laboratory of Cambridge University in England. Watson joined Francis Crick in this work in
