Human Genome Project - The DNA Sequence Has Been Revealed

After years of multi-billion-dollar research, the Human Genome Project and Celera Genomics (a non-government biotechnology company) jointly announced drafts of the human genome sequence in 2000. By mid-2001, scientists associated with these ventures had presented the true nature and complexity of the digital code inherent in DNA. We now understand that there are approximately 35,000 genes in each human DNA molecule, comprised of approximately 3 billion chemical bases arranged in precise sequence. Even the DNA molecule for the single-celled bacterium, E. coli, contains enough information to fill all the books in any of the world's largest libraries. We now appreciate that the DNA structure is one of the greatest scientific discoveries of all time, only first discovered at its base level in 1953 by James Watson and Francis Crick.
