Shows how scientists are learning to manipulate the fundamental processes of life and how biotechnology has led to new drugs and materials. Also mentions that research and development costs can be prohibitive.
Shows how DNA is extracted and purified before being analysed using electrophoresis. Southern blotting and probing of the DNA using a radioactively labelled probe. These techniques form the basis of DNA...
Biotechnology could shape the next century, but new organisms can run out of control and upset the ecological balance. Discusses a new safety test - ‘the fourth hurdle’ - and examines the environmental...
Looks at attempts to create food products through biotechnology. Genetic engineers claim that food shortages in the developing countries could be overcome by transferring genes from plants which can survive...
Looks at the technology of biosensors - the electronic harnessing of the body’s ability to monitor its own chemistry. Biosensor technology has implications for health care, industry, food and environment.
The bacteria ‘Escherichia coli’ has been made to produce human insulin by inserting the gene (the piece of DNA carrying a chemical code for human insulin). The programme explains the scientific...
Following a brief history of biotechnology, explores the various new techniques being developed and describes their present and projected applications. The process of cell manipulation is described in detail...
