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.

Ntawm qhov chaw twg tsis pom los ntawm qhov pom sab hauv?
Lub qhov ntswg zoo tshaj plawsyog nyob tom qab thiab yog li tsis pom nyob rau sab xub ntiag. Cov duab 9.1, 9.3, 9.5, 9.7, thiab 9.10 N/A Pab txhawb rau anterior cranial fossa; tsim ib feem ntawm qhov ntswg septum thiab qhov ntswg kab noj hniav;
Nyob rau qhov chaw nyob ze rau qhov pom?
Kev nyob ze ze Lub zeem muag Qhov kev pab cuam reflex (lossis nyob ze teb) yog peb feem reflexuas coj cov khoom ze rau hauv kev tsom los ntawm lens thickening, pupillary constriction, thiab sab hauv kev sib hloov ntawm qhov muag-qhov muag convergence.
Qhov qhov muag tsis pom ntawm lub tsheb thauj khoom nyob qhov twg?
Tsev tsheb ciav hlau qhov muag tsis pom muaj xws li: Ncaj nraim rau pem hauv ntej ntawm lub tsheb thauj khoom mus txog 20 ko taw Ncaj nraim hauv qab lub tsheb thauj khoom li 30 ko taw Txhua sab ntawm lub tsheb thauj mus rau sab nraub qaum Tam sim ntawd hauv qab thiab qab tus neeg tsav tsheb qhov rais Puas muaj qhov muag tsis pom kev tsheb thauj mus los?
Qhov kev pom twg pom kev tsis sib haum xeeb yog qhov tsim nyog?
Thaum tib neeg kev sib raug zoo pom tau txais kev sib haum xeeb ntawm lub koom haum ua ib feem tseem ceeb, kev sib cuam tshuam kev pom ntawm-kev tsis sib haum xeeb ntawm lub koom haum yuav siv tib lub tswv yim ib kauj ruam ntxiv. Nws qhia tias qhov kev tsis sib haum xeeb tsis tu ncua, tsawg kawg yog qhov tsim nyog thiab muaj txiaj ntsig zoo rau ib pab pawg .
Dab tsi yog qhov txawv ntawm kev pom tsis pom thiab pom tsis pom ntau dua?
Kev muaj peev xwm tawm tsam yam tsis muaj qhov kawg ntawm kev sau ntawv vs kev tuaj yeem cuam tshuam rau lwm tus neeg kuj yog qhov sib txawv. Qhov tseem ceeb Invisibility yog "qhov tseeb nrhiav / nkaum / mus ncig tsis pom" qhov twg Qhov Kev Pom Zoo Tshaj Plaws yog ntau ntawm kev sib ntaus sib tua Puas pom qhov tsis pom kev ua haujlwm ntawm kev pom tsis pom ntau dua?
