Genetics and Genomics Timeline
Introduction
From genes to genomes
The decoding of the human genome is a story that really begins in the nineteenth century with Darwin’s studies of heredity and Mendel’s peas. Milestones along the way include the discovery, in 1908, that genetic defects cause many inherited diseases. And in the Sixties, Marshall Nirenberg cracked the A’s, C’s, T’s and G’s of our genetic code. Modern DNA sequencing began in 1977 with the advent of new technologies for rapidly decoding DNA. A decade later, a bacterium became the first organism to have its genome sequenced. In 2000, the fruit fly was sequenced using the “whole-genome shotgun method.” The human genome was published in draft form in 2001, and since then the sequence has been refined and improved so that it is now essentially complete.
