The production of many copies of a DNA template.

Explanation:

PCR stands for Polymerase Chain Reaction and is used to produce a multitude of copies (amplification) of a certain piece of DNA that you want to analyse or use in experiments.

In the image below you can see that you need only one piece of DNA to start with; the amount of copies increases exponentially in each cycle. Usually between 20 and 35 cycles are used to produce sufficient DNA for analysis.
