Have you ever wondered how scientists study DNA or detect tiny traces of viruses as well as bacteria? How can they work with such small samples and still get clear answers? The answer often lies in PCR kits. The kits that are used for PCR purposes are a special kind of tools that help make many copies of DNA from just a tiny amount. This makes it possible for doctors, researchers, and labs to test, study, and discover very important information quickly as well as accurately.
