qauv ntawm cov kab mob … ntawm cov protein subunits hu ua capsomeres, uas feem ntau koom nrog, lossis pom ze rau, virion nucleic acid.
Pob cov cell muaj capsomeres?
Thaum tus kab mob kis tau nkag mus rau hauv lub xov tooj ntawm tes, host cellular enzymes zom cov capsid thiab nws cov capsomeres, yog li nthuav tawm cov khoom siv caj dab liab qab (DNA / RNA) ntawm lub tus kab mob, uas tom qab ntawd nkag mus rau lub voj voog rov ua dua.
cov kab mob capsid feem ntau pom nyob qhov twg?
Capsid sib dhos yuav siv qhov chaw nyob rau hauv lub nucleus, qhov chaw ntawm genome replication. Capsid los ua ke yog complex, thiab tshwm sim nrog kev pab los ntawm scaffold proteins. Nascent capsids muaj cov kab mob DNA (los ntawm lub portal complex) hauv cov txheej txheem uas yuav tsum tau muaj zog.
Tus kab mob capsomeres yog dab tsi?
Capsomere: Cov pawg ntawm cov subunits ntawm capsid raws li pom hauv electron micrographs; kuj hu ua Morphological subunit. Encapsidation (los yog encapsulation): Cov txheej txheem ntawm kev kaw cov kab mob genomic nucleic acid nyob rau hauv cov kab mob-encoded protein feem ntau tsim cov kab mob.
Lub xovtooj twg muaj lub capsid?
A capsid yog protein plhaub ntawm tus kab mob, kaw nws cov khoom siv caj ces. Nws muaj ob peb oligomeric (rov ua dua) cov qauv subunits ua los ntawm cov protein hu ua protomers. Cov kev soj ntsuam 3-dimensional morphological subunits, uas tej zaum yuav los yog tsis sib haum mus rau ib tug neeg cov proteins, hu ua capsomeres.
