Depicted in this 2007 photograph, Centers for Disease Control and Prevention (CDC), Acting Associate Director for Laboratory Science, microbiologist Dr. Hsi Liu (left), and staff biologist Damian Danavall, were shown performing a real-time PCR (polymerase chain reaction) assay using a 96-well plate format. PCR produces large amounts of replicated DNA or RNA molecular sequences. Using this process, very small amounts of these nucleic acid molecules can be analyzed upon the completion of the replication process. Both Dr. Liu and Mr. Danavall are National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention (NCHHSTP) staff members, inside the center’s Laboratory Reference and Research Branch (LRRB).
