Qhov yooj yim tshaj plaws virions muaj ob yam tseem ceeb: nucleic acid (ib zaug-los yog ob-stranded RNA lossis DNA) thiab protein ntau coat, ua capsid , uas ua haujlwm raws li lub plhaub los tiv thaiv tus kab mob genome los ntawm nucleases thiab uas thaum lub sij hawm kis kab mob txuas cov virion rau cov receptors tshwj xeeb nthuav tawm ntawm tus tswv tsev yav tom ntej.

Hauv qhov no, cov khoom tseem ceeb ntawm tus kab mob yog dab tsi?

Tus Kab Mob Tus Qauv. Tag nrho cov kab mob muaj ob yam nram qab no: 1) a nucleic acid genome thiab 2) a protein ntau capsid uas npog lub genome. Ua ke qhov no hu ua nucleocapsid. Tsis tas li ntawd, ntau yam kab mob tsiaj muaj 3) lipid hnab ntawv.

Ib sab saum toj no, 4 yam tseem ceeb ntawm tus kab mob yog dab tsi? Ntsiab Cov ntsiab lus Kab mob tau muab cais ua plaub pawg raws li cov duab: filamentous, isometric (los yog icosahedral), lub hnab, thiab lub taub hau thiab tus Tsov tus tw. Ntau kab mob txuas mus rau lawv cov tswv cuab tswv yim txhawm rau pab nkag mus ntawm cov cell membrane, tso cai rau lawv rov ua dua hauv lub cell.
