Kwintsimi ehlala iguquguquka ye-biology ye-molecular, i-Polymerase Chain Reaction (PCR) kunye ne-Gel Electrophoresis ziye zavela njengeendlela zembombo eziququzelela ukufundwa kunye nokuguqulwa kwe-DNA. Ezi ndlela zokufundisa azibandakanyi kuphando kuphela kodwa zikwanosetyenziso oluxhaphakileyo kuxilongo, isayensi yophando, kunye ne-biotechnology.

I-PCR yindlela yokuguqula ephuhliswe nguKary Mullis ngo-1983, evumela izazinzulu ukuba zandise icandelo elithile le-DNA ngokukhawuleza. Inkqubo iqala nge-denaturation ye-DNA, apho i-DNA ephindwe kabini ifudumala ukuya kwi-94 ° C, ibangela ukuba ihlukane ibe yimicu emibini enye. Oku kulandelwa yi-annealing, apho iiprimers-ezifutshane ezilandelelanayo ze-nucleotides-zibophelela kulandelelwano oluhambelanayo kwi-DNA enomgca omnye kwiqondo lobushushu elisezantsi (ngokuqhelekileyo malunga ne-55 ° C). Ekugqibeleni, isigaba sokwandisa senzeke kwi-72 ° C, apho i-enzyme ye-DNA polymerase idibanisa i-strand entsha ye-DNA ngokongeza i-nucleotides kwii-primers. Lo mjikelo uphindwa ngamaxesha angama-20-40, okukhokelela kwizigidi zeekopi zokulandelelana kwe-DNA ekujoliswe kuyo.
Emva kokuba i-DNA ikhulisiwe, i-Gel Electrophoresis iqeshwe ukwahlula kunye nokuhlalutya iimveliso ze-PCR. Obu buchule bubandakanya ukufuduka kwamaqhekeza e-DNA ngokusebenzisa i-agarose gel matrix phantsi kwefuthe lentsimi yombane. Iimolekyuli ze-DNA zihlawuliswa kakubi ngenxa yomqolo we-phosphate, kwaye zifudukela kwi-electrode elungileyo. Ijeli isebenza njengesefu, ivumela amaqhekeza amancinci e-DNA ukuba ahambe ngokukhawuleza kunamakhulu. Ngenxa yoko, amaqhekeza e-DNA ahlukana ngokusekelwe kubukhulu bawo, kunye neebhanti ezicacileyo ezibonakala phantsi kokukhanya kwe-ultraviolet emva kokungcoliswa kwedayi efana ne-ethidium bromide.

Indibaniselwano yePCR kunye neGel Electrophoresis inamandla kwizicelo ezininzi. Kwi-diagnostics yonyango, i-PCR isetyenziselwa ukufumanisa ubukho be-pathogens, ukuguqulwa kofuzo, okanye ulandelelwano oluthile lwe-DNA oluhambelana nesifo. I-Gel Electrophoresis ke ivumela ukubonwa kunye nokuqinisekiswa kwezi ziqwenga ze-DNA ezandisiweyo. Kwinzululwazi yezobungcwalisa, obu buchule bubalulekile kwi-DNA yeminwe, apho inceda ukutshatisa iisampulu ze-DNA ezivela kwiindawo zolwaphulo-mthetho kunye nezo zabarhanelwa.
