PCR me, ASAP! So we’ve removed the DNA from the cells, now what?
P C R • PCR = Polymerase chain reaction. • Used to make scrimillions of copies of the loci of interest.

This is amplification. Technically, this is not a science term either. Amplify: Root words Amplus, large + facere, to make* So we can just keep splitting it open and adding bases and make millions and millions of copies. *Webster’s New World Compact School and Office Dictionary, at 15, (1989)
The loci we care about are tagged with a flourescent dye. . . Holt Science and Technology, Life Science, p. 137
