Kuyini ukuhlolwa kwe-PCR?
I-PCR imane nje isho ukuthi "polymerase chain reaction". Lokhu kuhlolwa kusebenzisa imijikelezo yokufudumeza nokupholisa ukuthola ama-photon akhishwa lapho i-reagent (binder) RNA ibopha i-RNA yegciwane ekhishwe kusampula lomuntu. Umjikelezo ngamunye wokushisa nokupholisa ukhulisa (ukukhulisa) inani lezinto zofuzo ezihlosiwe esithubeni sokuhlola. Uma amandla ama-photon engafinyeleli kumkhawulo ngemuva kwenani elithile lemijikelezo, ukuhlolwa kwe-PCR kuzoholela kumphumela wokuhlolwa othi "Akutholakali".
