DESCRIPTION
Detecting a single DNA sequence demands high sensitivity. DNA amplification is used to generate thousands of DNA copies so that it can be easily detected and identified. To do so, scientists often employ a technique called polymerase chain reaction (PCR). This method requires specific equipment, including a heat source, because of the alternate cycles of high and low temperatures needed to perform it.
