The rediscovery of Mendel's work in 1900 began a series of revelations aboutthat would continue throughout the 20th century. What were some of these revelations?
Sir Paul Nurse
The story ofis an extraordinary one. It is almost certainly, without doubt, the greatest story of the 20th century in biology, with working out the classical laws of genetics and then the discovery of , deoxyribonucleic acid, as the basis of hereditary material.
DNA is made up of a series of letters - you can view it as a series of letters. Those letters encode information exactly as Mendel's particles predicted. And then these particular letters can be spelt out in a language, called the Central Dogma, where copies are made into and then the RNA is translated into , where the order and type of amino acids [the basic building blocks of proteins] is determined by the sequence of letters in the DNA. And because those proteins determine the characteristics of an organism, now we begin to understand how genes can work.
