1970s: Gene technology takes off

The 1970s saw the birth of Thatcherism - and the birth of genetic engineering. In 1973 American scientists Herbert Boyer and Stanley Cohen took genes from one organism and introduced them into another using special cutting and pasting proteins.

In 1977 - the year that Margaret Thatcher was so impressed by the young William Hague - Fred Sanger and Alan Coulson discovered a rapid technique to read the bases in genetic code. DNA sequencing was born.
