A plasmid yog ib tug me me, ncig, ob-stranded DNA molecule uas txawv ntawm ib tug cell chromosomal DNA. Cov kab mob kuj tuaj yeem hloov plasmids rau ib leeg los ntawm tus txheej txheem hu ua conjugation.

Ua li no, dab tsi yog qhov hloov vector?

Cov hloov vector encodes cov noob ntawm kev txaus siab thiab muaj cov sequences uas yuav koom ua ke rau hauv tus tswv tsev genome, tab sis tsis tuaj yeem tsim cov kab mob ua haujlwm tsis muaj cov noob encoded hauv lub hnab ntawv thiab ntim khoom. cov duab.

Tom qab ntawd, lo lus nug yog, dab tsi yog plasmid thiab nws txoj haujlwm yog dab tsi? A plasmid yog ib tug me me DNA molecule nyob rau hauv ib lub cell uas yog lub cev sib cais los ntawm chromosomal DNA thiab replicate nws tus kheej. Hauv qhov xwm txheej, plasmids feem ntau nqa cov noob uas muaj txiaj ntsig zoo rau kev ciaj sia, xws li los ntawm kev muab tshuaj tua kab mob.

Kuj tseem paub yog, ntim plasmid yog dab tsi?

Ib lossis ntau dua plasmids , feem ntau hu ua ntim plasmids , encode cov virion proteins, xws li lub capsid thiab rov qab transcriptase. Lwm tus plasmid muaj cov khoom genetic khoom xa los ntawm vector. Cov kab ke no yog siv los ntim cov genome rau hauv virion.

Dab tsi yog lentiviral plasmid?

Nrov Lentiviral Hloov Plasmids Thaum twg lentivirus yog siv rau kev tshawb fawb, nws yog tus lentiviral genome uas encodes genetic khoom uas tus kws tshawb fawb xav tau xa mus rau cov hom phiaj tshwj xeeb. Qhov no genome yog encoded los ntawm plasmids hu ua "transfer plasmids , "uas tuaj yeem hloov kho kom nkag siab ntau yam ntawm cov khoom siv noob.
