DNA Recognition Instruments
█
AGNIESZKA LICHANSKA
DNA recognition instruments allow rapid identification of the origin of DNA in an environmental or medical sample. Recognition of the source of DNA is important in pathogen (disease-causing agent) identification in public health surveillance, and diagnostic and military applications.
DNA recognition instruments utilize two main methods for DNA detection and identification, nucleic acid hybridization r polymerase chain reaction (PCR). Hybridization of nucleic acids allows differentiation of sequences that differ by as little as one base pair by using high temperature washes that remove partially matched DNA strands. ...
