Just imagine ......
a technology enabling us to extract a tiny quantity of DNA from a single hair or drop of blood at the scene of a crime and increase the amount of it a million times or more so that it can be analysed
a technology allowing us to analyse the DNA from a bacterial or viral infection in order to diagnose an illness
a technology that makes it possible to mass-produce DNA from fossil remains, extinct for millions of years
This technology exists - it is the polymerase chain reaction.
