Description:Depicted in this 2007 photograph was CDC biologist Damian Danavall, as he was performing a multiplex real-time PCR assay that can differentiate between four sexually transmitted organisms causing genital ulcerations. PCR, or polymerase chain reaction, 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.
Mr. Danavall is a National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention (NCHHSTP) staff member, who works inside the center’s Laboratory Reference and Research Branch (LRRB).
