By working on the Wolbachia Project, students will become familiar with basic lab skills like pipetting, setting up a PCR protocol, and running gel electrophoresis. Since the polymerase chain reaction (PCR) was first described in 1985, the technique and its applications have gone through many rounds of their own amplification. PCR is based on using the ability of DNA polymerase to synthesize new strand of DNA complementary to the offered template strand. Multiplex PCR was established for differential diagnosis of taeniasis and cysticercosis, including their causative agents.
