PCR: Persistent Crazy Replicaters

"The PCR Song" from Bio-Rad for crazy scientists
Most scientists think PCR as "polymerase chain reaction";
Actually, it is "persistent crazy replicaters";
That's how the world is produced.
  
Lyrics:
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. (Hahahahahahaha~~~~, most funny part~~~~)
PCR, when you need to solve a crime.

(repeat chorus) (less)
