Tso daim duab sib sau ua ke ntawm tus mob coronavirus tshiab. Lub cim xiav qhia cov kab mob. Cov xim dub me me hauv cov kab mob yog cov nucleic acids ntawm ntu ntuag, uas yog cov seem ntawm tus kabmob coronavirus uas muaj cov genome. Qhov genome no tseem ceeb heev rau peb qhov kev tshawb nrhiav thiab yog cov khoom siv hauv peb qhov kev tshawb nrhiav.
Kev kuaj mob molecular yog ib feem tseem ceeb ntawm kev kuaj mob. Kev kuaj mob yog ib qho teeb meem nyuaj, tshwj xeeb tshaj yog thaum cov kab mob tshiab tshwm sim. Rau cov kab mob sib kis, kev kuaj mob molecular tau dhau los ua qhov ntsuas tseem ceeb heev thaum paub tus kab mob. Nws lub hom phiaj tseem ceeb yog raws li hauv qab no: ua ntej, nws txiav txim siab seb cov tsos mob tshwm sim, xws li kub taub hau, yog tshwm sim los ntawm COVID-19, kom nws tsis tuaj yeem cuam tshuam nrog lwm yam kab mob. Qhov thib ob, qhov zoo (xws li qhov zoo thiab qhov tsis zoo) lossis cov lus piav qhia ntau ntawm cov txheej txheem kab mob, xws li tus nqi ntawm tus kab mob load. Thib peb, los ntawm kev ua kom zoo dua qub, qee qhov kev kuaj mob molecular kuj tuaj yeem muab cov txheej txheem kho mob, pab txiav txim siab nws cov tswv yim thiab muab pov thawj txhawb nqa. Plaub, los ntawm kev xav ntawm cov kab mob kis, peb tuaj yeem taug qab qhov kev hloov pauv, uas tseem ceeb heev. Peb tuaj yeem kawm thiab kwv yees qhov kev hloov pauv ntawm kev kis kab mob thiab cov kab mob pathogenicity ntawm tus kab mob hauv cov txheej txheem ntawm kev sib kis.
Kev kuaj mob molecular yog dab tsi? Kev kuaj mob molecular hauv qhov nqaim feem ntau yog kuaj pom nucleic acid. Nucleic acid nrhiav pom yog hais txog kev sim seb puas muaj ib ntu ntawm DNA lossis RNA tawg hauv cov qauv ua pov thawj ntawm cov kab mob pathogenic.
