Cette méthode de Biologie Moléculaire a été mise au point en 1985 par Kary Mullis, qui obtint pour ces travaux le prix Nobel de Chimie en 1993. Aujourd’hui, ce procédé révolutionnaire couplé à l’utilisation d’une ADN polymerase thermorésistante permet d’obtenir, sans clonage, une amplification considérable d’un fragment donné d’ADN.

Et pour s'entrainer voici les paroles :
There was a time when to amplify DNA,
You had to grow tons and tons of tiny cells.
(Oooh) Then along came a guy named Dr. Kary Mullis,
Said you can amplify in vitro just as well.
Just mix your template with a buffer and some primers,
Nucleotides and polymerases too.
Denaturing, annealing, and extending,
Well it’s amazing what heating and cooling and heating will do.
[Chorus]
PCR when you need to detect mutation (detect mutation)
PCR when you need to recombine (recombine)
PCR when you need to find out who the daddy is (who’s your daddy?)
PCR when you need to solve a crime (solve a crime)
[x2]
