Dab tsi yog plasmid

Ib lub plasmid yog ib qho me me vas lwg pom hauv cov kab mob thiab qee lwm cov tsiaj ntawv me me. Lawv feem ntau muaj tsawg tus ntawm cov noob caj noob - (qee qhov cuam tshuam nrog cov tshuaj tua kab mob tsis kam - thiab tuaj yeem hla dhau ib lub xovtooj ntawm lwm tus.

Plasmid yog ib qho ntawm cov kauj ruam tseem ceeb hauv kev tsim cov cell cov tshuaj xws li lub tsheb - T hlwb, ua kom muaj kev tsim khoom zoo li muaj ntau lawm, kev tshuaj xyuas.

Kev tswj kom zoo ntawm plasmid thev naus laus zis

Kev tswj hwm zoo ntawm lub plasmid thev naus laus zis yog cov txheej txheem tseem ceeb kom ntseeg tau tias cov tsim cov hom phiaj ua tau raws li lub hom phiaj thiab muaj txiaj ntsig zoo thiab ua tau zoo ib yam. Cov khoom siv tswj tau zoo ntawm cov tshuab plasmid feem ntau suav nrog pH tus nqi, cov ntsiab lus ntawm tes ntawm Cell RNA, cov lus tseem ceeb (cov kab mob endotoxin, thiab lwm yam.
