Biotechnology concerns the practical application of organisms or their
components. Historically, biotechnology was an art, involved in the
production of wines, beers and cheeses. Nowadays it involves a series of
advanced technologies spanning biology, chemistry, and process
engineering. In recent years innovations involving genetic engineering
have had a major impact on biotechnology. Its applications are diverse,
including the production of new drugs, transgenic organisms and
biological fuels, gene therapy and clearing up pollution. John Smith,
writing in a readily accessible way, describes the history, techniques
and applications of biotechnology as well as discussing the ethical
issues raised by this modern science. The third edition of this
successful book has nearly doubled in size to take account of recent
advances. It is important reading for anyone, from school onwards,
interested in this field.
