Cov kab mob feem ntau muaj icosahedral lossis helical capsid qauv, txawm hais tias ob peb muaj complex virion architecture. Ib qho icosahedron yog tus duab geometric nrog 20 sab, txhua qhov tsim los ntawm daim duab peb sab sib npaug, thiab cov kab mob icosahedral nce tus naj npawb ntawm cov qauv hauv txhua lub ntsej muag kom nthuav dav capsid loj.
piv txwv ntawm tus kab mob icosahedral yog dab tsi?
Cov kab mob nrog cov qauv icosahedral raug tso tawm rau hauv ib puag ncig thaum lub cell tuag, tawg thiab lyses, yog li tso cov virions. Piv txwv ntawm cov kab mob nrog cov qauv icosahedral yog poliovirus, rhinovirus, thiab adenovirus.
Icosahedral hais dab tsi?
(a) particles nrog ntau tshaj xya crystalline bonds(b) Ib tug raug configuration ntawm daim ntawv cog lus hais hais. Icosahedral hais yog qhia nyob rau hauv tib xim yog hais tias lawv koom nyob rau hauv tib pawg. Yog hais tias ib tug particle nyob sib ze ob qho tib si crystal-zoo li thiab icosahedral qauv, nws yog tso tawm raws li icosahedral.
3 tus kab mob yog dab tsi?
Feem ntau, cov duab ntawm cov kab mob tau muab faib ua plaub pawg: filamentous, isometric (los yog icosahedral), lub hnab, thiab lub taub hau thiab tail.
Tus kab mob tsawg tshaj plaws yog dab tsi?
Cov kab mob me tshaj plaws ntawm cov genome loj yog ib leeg-stranded DNA (ssDNA) viruses. Tej zaum qhov nto moo tshaj plaws yog bacteriophage Phi-X174 nrog genome loj ntawm 5386 nucleotides.
