Problem
Patients can be infected with various bacteria, viruses, fungi, or protozoa. Identify one of these organisms from patient samples using the polymerase chain reaction. What tissue is the sample taken from, and what must be done to prepare a PCR reaction? You may base your answer on the laboratory protocol listed in the online lab, "Bacterial Genetics: Transformation and Confirmation Using Polymerase Chain Reaction and Agarose DNA Gel Electrophoresis."
