Revolution of rDNA technology

One of the great achievements of modern science has been the sequencing of the human genome, which was largely completed by 2003. The sequencing of the first complete genome, that of a bacterium, had been achieved in previous years. During the intervening years, researchers accelerated the pace of DNA sequencing, while working on other genomes, aided by the development of faster and faster sequencing machines. These sequencing accomplishments have all depended on advances
in DNA technology, starting with the invention of methods for making recombinant DNA. This is DNA in which nucleotide sequences from different sources – often different species – are combined in vitro into the same DNA molecule.
