. Polymerase chain reaction (PCR) provides a powerful technique for identifying viruses and studying the homology between viral nucleic acids. Tissue printing and dot blot are simple techniques to detect miRNA expression and localization, allowing a better understanding of the function of a miRNA. Additional Online Courses.
