Britain is a nation of inventors, from the thermos flask by
Sir James Dewar in 1802, to the vacuum cleaner by Hubert
Cecil Booth in 1909- both inventors I’m sure you’re likely
to have never heard of as their inventions were not of
great significance. However even British inventors who’s
innovative ideas have had a major impact on our world today
are unknown, and so here is a rundown of a couple of our
most influential inventions, which will hopefully boost the
pride you have in this great country.
DNA profiling was discovered in 1984 by Sir Alec Jeffery’s at
the University of Leicester. DNA profiling (also called DNA
finger printing, DNA testing, or DNA typing) is a forensic
technique used to identify individuals by characteristics
of their DNA. Even though it is used in less than 1% of all
criminal cases, DNA profiling has helped to acquit or convict
suspects in many of the most violent crimes, including
countless rapes and murders. When used correctly, DNA
profiling is a powerful forensic tool. It can be used to quickly
eliminate a suspect, saving time in searches for perpetrators.
It can also provide compelling evidence to support a
conviction and, most importantly, reduce the chances of
a wrongful conviction. Here is a real life case where DNA
DNA fingerprints
of two children,
the bands marked
in blue match the
father and the bands
marked in red match
the mother.
