Falcelinta Silsiladda Polymerase (PCR) Tallaabooyinka Habka Falcelinta Silsiladda Polymerase, oo si weyn loogu yaqaan PCR, waxay ka dhigan tahay mid ka mid ah horumarka tignoolajiyada ugu muhiimsan ee taariikhda bayoolaji molecular. Waxaa la sameeyay 1980-meeyadii, farsamadani waxay ka gudubtay nidaamka shaybaadhka ee gaarka ah una gudubtay Sii akhri

Mashiinka PCR waa aalad shaybaar oo adeegsasa baaskiil wadida heerkulka saxda ah si loo fududeeyo falcelinta silsilada Polymerase, taasoo awood u siinaysa in si degdeg ah loo kordhiyo DNA-ga gaarka ah ama taxanaha RNA ee falanqaynta. Adiga oo otomaatig u ah wejiyada kululaynta iyo qaboojinta ee looga baahan yahay denaturation, ka saarista, iyo fidinta, a Sii akhri

Aragtida ka danbaysa tamashlaha biyaha hoostooda waxay ku salaysan tahay afar mabda'a oo udub dhexaad u ah dhaqdhaqaaqa dareeraha: buoyancy, cadaadiska hydrostatic, viscosity, iyo thermodynamics. Cutubyadani waxay si isku mid ah u shaqeeyaan si ay u yareeyaan culeyska culeyska ee kala goysyada ilaa 80%, kordhiyaan iska caabbinta murqaha ee dhismaha xoogga, iyo i Sii akhri

Faa'iidooyinka aasaasiga ah ee socodka biyaha hoostooda ee eyda waxaa ka mid ah saamaynta hoos u dhaca kala-goysyada iyada oo loo marayo rabitaanka, korodhka caabbinta muruqa ee xoojinta, hagaajinta kala duwanaanta dhaqdhaqaaqa, iyo dardargelinta wakhtiyada soo kabashada bukaannada qalliinka kadib.

Goobta daaweynta jireed ee canine iyo jirdhiska ayaa arkay isbedel weyn oo ku wajahan daaweynta biyaha sannadihii la soo dhaafay. Sida milkiilayaasha xayawaanka iyo xirfadlayaasha caafimaadka xoolaha ay raadinayaan habab waxtar leh oo lagu maareeyo caafimaadka canabka, eyga lagu tumanayo biyaha hoostooda ayaa u soo baxay xal heersare ah.
