Bacteriophages yog tsim ntawm cov proteins uas encapsulate DNA los yog RNA genome, thiab tej zaum yuav muaj cov qauv uas yooj yim los yog elaborate.
Tsis tas li ntawd, bacteriophages tsim li cas?
Qhov ntev tail fibers yog siv los ntawm cov kab mob bacteriophage mus txuas nws tus kheej mus rau cov kab mob thiab tus kab mob ces ntxig nws cov khoom genetic khoom nyob rau hauv lub host cell pib lub replication txheej txheem. Cov kab mob bacteriophage siv tus tswv tsev cell rov ua dua thiab ua ntau dua cov kab mob bacteriophages.
Tsis tas li ntawd, cov kab mob bacteriophages puas tsim kev puas tsuaj rau tib neeg? Bacteriophages muaj ntau yam tshwj xeeb tshaj li cov tshuaj tua kab mob. Lawv feem ntau tsis muaj kev phom sij tsis yog rau tus tswv tsev nkaus xwb tab sis kuj rau lwm cov kab mob uas muaj txiaj ntsig zoo, xws li lub plab flora, txo txoj kev pheej hmoo kis mob.
Ntawm no, bacteriophages ua dab tsi?
A kab mob bacteriophage yog ib hom kab mob uas kis kab mob. Qhov tseeb, lo lus " kab mob bacteriophage "lus txhais tau tias "tus kab mob noj," vim cov kab mob bacteriophages rhuav tshem lawv cov cell. Tag nrho cov kab mob bacteriophages yog tsim los ntawm nucleic acid molecule uas yog surrounded los ntawm cov qauv protein.
Dab tsi ua rau bacteriophage tshwj xeeb?
Bacteriophages yog "cov kab mob noj" nyob rau hauv uas lawv yog cov kab mob uas kis tau thiab rhuav tshem cov kab mob. Qee zaum hu phages , cov kab mob microscopic no yog ubiquitous nyob rau hauv qhov. Ntxiv nrog rau kev kis kab mob, cov kab mob bacteriophages kuj kis tau lwm yam microscopic prokaryotes hu ua archaea.

Cov kab mob puas kis cov kab mob eukaryotic?
Ib lub cell uas muaj kab mob ua rau cov kab mob kis tau ntau dua thiab cov khoom siv caj ces es tsis yog nws cov khoom qub. Qee cov kab mob yuav nyob twj ywm hauv cov tswv tsev rau lub sijhawm ntev, ua rau tsis muaj kev hloov pauv hauv lawv cov tswv tsev (ib theem hu ua lysogenic theem). Cov kab mob ua rau muaj ntau yam kab mob hauv eukaryotes
Cov tshuaj tua kab mob twg thaiv cov kab mob protein ntau?
Tetracyclins yog ib hom tshuaj tua kab mob uas suav nrog cov thawj tetracycline nrog rau doxycycline thiab minocycline. Cov tshuaj tua kab mob no khi rau A qhov chaw ntawm 30s ribosome, tiv thaiv tRNA los ntawm kev nqa cov amino acids tshiab. Yog tias tRNA tsis tuaj yeem txuas mus rau ribosome, ces tsis muaj cov proteins tshiab tuaj yeem ua tau
Cov kab mob twg muaj cov kab mob eukaryotic?
Cov kab mob thiab Archaea tsuas yog prokaryotes. Cov kab mob uas muaj eukaryotic hlwb hu ua eukaryotes. Tsiaj txhu, nroj tsuag, fungi, thiab protists yog eukaryotes. Tag nrho cov kab mob multicellular yog eukaryotes
Cov kab mob thiab cov kab mob ua haujlwm zoo li cas?
Ob leeg cov kab mob thiab cov kab mob muaj cov phab ntsa ntawm tes (txawm hais tias sib txawv hauv cov qauv thiab muaj pes tsawg leeg) Feem ntau cov kab mob thiab cov kab mob tau txais lub zog los ntawm kev ua pa aerobic (ua pa hauv cov kab mob me ntsis txawv dua li hauv Eukaryotes tab sis cov pa oxygen ib txwm xav tau rau oxidise suab thaj, hauv dej kawg. thiab carbon dioxide yog tsim)
Dab tsi yog cov kab mob piav qhia cov kab mob ntawm tes hauv kev nthuav dav?
Cov kab mob yog cov prokaryotes, tsis muaj cov nuclei zoo thiab cov kab mob sib txuas ua ke, thiab nrog cov chromosomes tsim los ntawm ib lub voj voog DNA kaw. Lawv tuaj nyob rau hauv ntau yam duab thiab ntau thiab tsawg, los ntawm feeb spheres, cylinders thiab kauv threads, rau flagellated rods, thiab filamentous chains
