This is hilarious, to those who know about DNA technology and the Polymerase Chain Reaction.
Its an advertisement done by BioRad and the singers are all scientists and researchers.
There was a time when to amplify DNA
You had to grow tons and tons of tiny cells
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
PCR, when you need to detect mutations
PCR, when you need to recombine
PCR, when you need to find out who the daddy is
PCR, when you need to solve a crime
