RFLP analysis was carried out on 36 rice elite line. Sterility of these 162 rice hybrids was studied in groups and in types.

Methods HBV genotypes were detected by polymerase chain reaction (PCR) and restriction fragment length polymorphism analysis (RFLP) in 136 HBV DNA positive patients who were born in Shanghai.

This paper summarizes the application of molecular biological techniques in the identification of Taenia, such as analysis of DNA sequence, PCR-RFLP and LAMP.
