Randomly amplified polymorphic DNA (RAPD)

RAPD is a molecular technique for polymorphism analysis of unknown genome based on polymerase chain reaction (PCR). RAPD is a commonly used method for molecular typing and traceability. Because RAPD is easy to operate and does not require specially designed primers, it provides a rapid, flexible and sensitive method for microbial strain-level typing for contaminant microorganism traceability in industrial production.
