摘要
The discovery of the structure of DNA transformed biology profoundly, catalysing the sequencing of the human genome and engendering a new view of biology as an information science. Two features of DNA structure account for much of its remarkable impact on science: its digital nature and its complementarity, whereby one strand of the helix binds perfectly with its partner. DNA has two types of digital information - the genes that encode proteins, which are the molecular machines of life, and the gene regulatory networks that specify the behaviour of the genes.
