Polymerase chain reaction (PCR) yog ib qho chaw kuaj mob siv los nthuav cov DNA sequences Cov txheej txheem cuam tshuam nrog kev siv luv DNA sequences hu ua primers los xaiv ib feem ntawm cov genome kom nthuav dav. … Cov txheej txheem tuaj yeem tsim tau ntau lab luam ntawm lub hom phiaj ib ntus hauv ob peb teev xwb.
Yuav ua li cas yog polymerase saw cov tshuaj tiv thaiv siv rau?
Polymerase saw cov tshuaj tiv thaiv, lossis PCR, yog cov txheej txheem kuaj siv los ua ntau daim ntawv luam ntawm ntu ntawm DNA. PCR yog qhov tseeb heev thiab tuaj yeem siv los nthuav tawm, lossis theej, ib lub hom phiaj DNA tshwj xeeb los ntawm kev sib xyaw ntawm DNA molecules.
Dab tsi yog polymerase saw cov tshuaj tiv thaiv yooj yim txhais?
Mloog cov lus.(puh-LIH-meh-rays chayn ree-AK-shun) Ib txoj hauv kev sim siv los ua ntau daim ntawv luam ntawm ib daim DNA los ntawm cov qauv uas muaj cov nqi me me ntawm DNA Cov tshuaj tiv thaiv kab mob Polymerase tso cai rau cov khoom DNA no kom nthuav dav kom lawv tuaj yeem kuaj pom.
PCR txhais li cas hauv kev kuaj Covid?
PCR txhais tau tias polymerase saw cov tshuaj tiv thaivNws yog ib qho kev sim txhawm rau txhawm rau txheeb xyuas cov khoom siv caj ces los ntawm cov kab mob tshwj xeeb, xws li tus kab mob. Kev kuaj xyuas pom muaj tus kab mob yog tias koj muaj tus kab mob thaum lub sijhawm kuaj. Kev kuaj kuj tseem tuaj yeem kuaj pom cov kab mob sib kis txawm tias tom qab koj tsis kis tus kab mob lawm.
Cov tshuaj tiv thaiv PCR yog dab tsi?
PCR ntiav ob lub ntsiab reagents - primers (uas yog luv luv ib leeg DNA tawg tawg hu ua oligonucleotides uas yog ib qho kev sib txuas ntxiv rau thaj tsam DNA) thiab DNA polymerase.
