James Watson :: DNA from the BeginningWatson 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. Their model enabled them to explain the molecular structure of nucleic acids, and also pinpoint DNA as the carrier of genetic information.

The Discovery of the Double Helix, 1951-1953
Not only are the DNA base pairs connected via hydrogen bonding, it was known well before the structure of DNA was determined that genes contain the instructions for producing proteins. The nitrogenous base is either a purine or biologu pyrimidine. As discussed above, but the outer edges of the nitrogen-containing bases are exposed and available for potential hydrogen bonding as well. The way in which the nucleotide subunits are lined together gives a DNA strand a chemical polarity.

The Evangelist of Molecular Biology
What to read about the molecule which serves as a depositary of the whole information about features of all living organisms as recommended by the Boston University professor Maxim Frank-Kamenetskii. The pivotal role of the DNA molecule stems from the fact that it and only it carries the whole information, and in all details, about the composition and properties of any living organism. Because of this, the knowledge of all features of the DNA structure is of a paramount significance. During the years passed since the discovery of the double helix the significance of the DNA science has grown enormously. The DNA analysis makes it possible to diagnose a host of hereditary diseases. Moreover, the entire huge industry of developing new drugs and new diagnostics and therapies of various diseases is based on the DNA science and technology. The reader, however, must keep in mind that it is a very subjective view of the events, which led to the one of the greatest scientific discoveries in the history of mankind.
