Cov proteins uas ua rau capsid yog hu ua capsid proteins lossis viral coat proteins (VCP). Lub capsid thiab sab hauv genome yog hu ua nucleocapsid. … Thaum tus kab mob no kis tau mus rau ib lub xovtooj ntawm tes thiab pib replicating nws tus kheej, tshiab capsid subunits yog synthesized siv cov protein biosynthesis mechanism ntawm lub cell.
Pob hlwb puas muaj capsids?
Nws muaj enzymes, los yog cov proteins, ua kom cov virion nkag mus rau hauv lub cell daim nyias nyias thiab thauj nucleic acid hauv cov hlwb. Lub capsid enclosing nucleic acid yog hu ua nucleocapsid, uas tuaj yeem suav tau tias yog tus kab mob kis tau thiab ua haujlwm.
pom capsids nyob qhov twg?
Capsid proteins yog synthesized ntawm ribosomes hauv cytosol thiab tuaj rau hauv lub nucleus uas lawv sib sau ua ke nrog scaffold proteins thiab ib lub portal protein los tsim cov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob.
Vim li cas cov kab mob muaj capsids?
Viruses muaj ntau yam yam ntxwv: lawv me me, muaj DNA lossis RNA genomes, thiab yog cov kab mob hauv lub cev. Tus kab mob capsid ua haujlwm los tiv thaiv nucleic acid los ntawm ib puag ncig, thiab qee tus kab mob nyob ib puag ncig lawv capsid nrog lub hnab ntawv membrane.
Puas muaj kab mob hauv cov hlwb?
Lawv yog tus tshwj xeeb vim lawv yog tsuas muaj sia nyobthiab muaj peev xwm sib npaug hauv cov hlwb ntawm lwm yam muaj sia. Lub cell uas lawv muab faib ua yog hu ua tus tswv cell. Tus kab mob yog tsim los ntawm ib qho tseem ceeb ntawm cov khoom siv caj ces,DNA lossis RNA, ib puag ncig los ntawm lub tsho tiv thaiv hu ua capsid uas yog tsim los ntawm cov protein.
Pom zoo:
Lub hlwb twg hauv qab no muaj nyob hauv tus neeg mob lub kaus mom?
Lub parietal epithelium ntawm Bowman's capsule yog txheej txheej sab nrauv thiab tsim los ntawm cov hlwb squamous epithelial yooj yim hu ua " parietal cells." Lub parietal txheej tsis ncaj qha cuam tshuam nrog kev pom los ntawm cov hlab ntsha.
Pob hlwb puas muaj protein ntau capsids?
Cov proteins ua up lub capsid hu ua capsid proteins lossis viral coat proteins (VCP). Lub capsid thiab sab hauv genome yog hu ua nucleocapsid. … Thaum tus kab mob no kis tau mus rau ib lub xovtooj ntawm tes thiab pib replicating nws tus kheej, tshiab capsid subunits yog synthesized siv cov protein biosynthesis mechanism ntawm lub cell.
Puas yog cov hlwb meristematic muaj nyob rau hauv lateral buds?
Meristematic cov ntaub so ntswg muaj nyob rau hauv ntau qhov chaw, suav nrog nyob ze ntawm lub tswv yim ntawm cov hauv paus hniav thiab stems (apical meristems), nyob rau hauv lub buds thiab nodes ntawm stems, nyob rau hauv lub cambium ntawm lub xylem thiab phloem nyob rau hauv dicotyledonous ntoo thiab shrubs, nyob rau hauv lub buds thiab nodes ntawm stems.
Lub hlwb puas hlwb nyob qhov twg?
A retinal ganglion cell (RGC) yog ib hom neuron nyob ze rau sab hauv (lub ganglion cell txheej) ntawm retina ntawm lub qhov muag. Nws tau txais cov ntaub ntawv pom los ntawm photoreceptors ntawm ob hom neuron nruab nrab: cov hlwb bipolar thiab amacrine cells.
Puas yog cov hlwb bulliform muaj nyob rau hauv dicots?
Teb tiav: Bulliform cells lossis lub cev muaj zog muaj nyob nyob rau saum npoo ntawm nplooj ntawm ntau cov monocots. Lawv yog cov loj, npuas-puab epidermal hlwb uas tshwm sim nyob rau hauv pawg nyob rau saum npoo ntawm nplooj ntawm ntau monocots.
