Molecular pathology
From Wikipedia, the free encyclopedia
Molecular pathology is an emerging discipline within anatomic pathology which is focused on the use of nucleic acid-based techniques such as DNA sequencing, fluorescent in-situ hybridization, reverse-transcriptase polymerase chain reaction, and nucleic acid microarrays for specialised studies of disease in tissues and cells. Molecular pathology shares some aspects of practice with both anatomic and clinical pathology, and is sometimes considered a "crossover" discipline.
