PCR, in one form or another, has become fairly routine. It's used for everything from cloning and mutating, to analyzing RNA expression, to identifying fossils and criminals. Tools for conducting standard PCR, real-time PCR (RT-PCR), and quantitative PCR (qPCR) have followed suit, and there are Web sites for designing and ordering primers or purchasing off-the-shelf kits. These days, it's just a matter of adding reagents and nucleic acids to a tube or plate, pushing "start," and checking the computer a little while later to look at your results.
