It’s the law of nature that whenever we grow something, after some time, it results in high returns and prosperity! May it be a small seed which grows as tree and give nutritive fruits, flowers, oxygen, etc or may it be our knowledge! But we as a man never knew that even the amplification (growth) of microscopic (invisible to naked eyes) DNA will give us so much of benefits such that it will bring revolution in the field of science! Yes that’s what happened with Polymerase Chain Reaction technology. PCR technology has not only proved its mettle in bringing the revolution in science but also has once again proved the same law of nature!
Today in modern world of PCR technology, samples of DNA are easily diagnosed for presence of genetic disease mutations. This not only helps in detection of cancers cells but also helps in its effective treatment by specifically identifying the mutant gene. Today PCR technology had helped a lot in Prenatal testing in which DNA can be easily obtained by chorionic villus sampling , amniocentesis or even by detection of rare fetal cells which are in mothers bloodstream and thus these can be easily amplified. PCR is used in tissue typing and has helped in diagnosis of immunological disorders and diseases. Many infectious diseases like HIV, Tuberculosis and endemic are easily diagnosed with the help of PCR. Genetic fingerprinting can easily identify any one person from the entire world population only because of PCR technology.
World is proud of Mullis for his "revolutionary" discovery of PCR. In 1993, Mullis was awarded the Nobel Prize in Chemistry for this excellence which is known as polymerase chain reaction - revolution in science!
