[单项选择]The first technological revolution in modern biology started when James Watson and Francis Crick described the structure of DNA half a century ago. That established the fields of molecular and cell biology, the basis of the biotechnology industry. The sequencing of the human genome nearly a decade ago set off a second revolution which has started to illuminate the origins of diseases.
Now the industry is convinced that a third revolution is under way: the convergence of biology and engineering. A recent report from the Massachusetts Institute of Technology says that physical sciences have already been transformed by their adoption of information technology, advanced materials, imaging, nanotechnolugy and sophisticated modelling and simulation. Phillip Sharp, a Nobel prize-winner at that university, believes that those tools are about to be brought to bear on biology too.
But the chances are that this will take time, and turn out to be more of a reformation than a revolution.
A. The molecular and cell structure are found during the first revolution.
B. Scientists sequenced the human genome half a century ago.
C. C. Scientists have completely understood the mystery of DN
D. The origins of some diseases have been found in the second revolution.
