Qhov sib txawv tseem ceeb ntawm bacteriophage thiab TMV yog cov kab mob bacteriophage yog tus kab mob uas kis tau cov kab mob tshwj xeeb thaum TMV yog tus kab mob uas kis tau rau haus luam yeeb thiab ntau yam nroj tsuag.
Kab mob yog cov kab mob me me uas rov ua dua hauv cov kab mob uas muaj sia nyob. Lawv yog cov kab mob hauv lub cev uas muaj peev xwm kis tau yuav luag txhua yam kab mob, suav nrog tsiaj, nroj tsuag, fungi, protozoa thiab kab mob. Lawv muaj cov protein capsid thiab DNA lossis RNA genome. Lub genome ntawm tus kab mob no tuaj yeem yog DNA lossis RNA, ib leeg-stranded lossis ob-stranded, ncig lossis linear. Tus kab mob bacteriophage yog tus kab mob uas tawm tsam cov kab mob thiab rov ua dua siv cov kab mob replication machinery. Bacteriophages yog cov kab mob ntau tshaj plaws hauv biosphere, thiab lawv tuaj yeem muaj DNA lossis RNA genomes. TMV lossis Tobacco Mosaic Virus yog cov kab mob cog qoob loo. Nws kis tau haus luam yeeb thiab ntau lwm yam nroj tsuag xws li qoob loo, ornamentals thiab nroj tsuag.
Bacteriophage yog dab tsi?
A bacteriophage (phage) yog ib tus kab mob uas kis tau thiab nthuav tawm hauv cov kab mob tshwj xeeb. Lawv kuj hu ua cov kab mob noj vim lawv ua cov kab mob bactericidal. Cov kab mob Bacteriophages tau tshawb pom los ntawm Frederick W. Twort hauv xyoo 1915, thiab lawv tau raug hu ua bacteriophages los ntawm Felix d'Herelle hauv xyoo 1917. Lawv yog cov neeg sawv cev tshaj plaws hauv ntiaj teb. Lawv yog tsim los ntawm genome thiab protein capsid. Bacteriophage genome tuaj yeem yog DNA lossis RNA, tab sis, feem ntau ntawm cov kab mob bacteriophages yog ob-kab DNA kab mob.
Bacteriophages yog tshwj xeeb rau ib tus kab mob lossis ib pawg kab mob tshwj xeeb. Lawv muaj npe nrog cov kab mob los yog cov kab mob uas lawv kis tau. Piv txwv li, bacteriophages uas kis tau E coli hu ua coliphages. Bacteriophages qhia cov duab sib txawv. Qhov zoo tshaj plaws yog lub taub hau thiab tus Tsov tus tw.
Daim duab 01: Bacteriophage
Bacteriophages yuav tsum kis tus tswv cell kom rov tsim dua. Lawv nruj nreem txuas rau ntawm phab ntsa ntawm cov kab mob uas siv lawv cov receptors saum npoo thiab txhaj lawv cov khoom siv caj ces rau hauv lub cell. Bacteriophages tuaj yeem dhau los ua ob hom kab mob xws li lytic thiab lysogenic voj voog. Nws nyob ntawm hom phage. Nyob rau hauv lub voj voog lytic, bacteriophages kis cov kab mob thiab tua cov kab mob sai sai los ntawm lysis. Nyob rau hauv lub voj voog lysogenic, cov khoom siv tshuaj tua kab mob ua ke nrog cov kab mob genome lossis plasmids thiab muaj nyob rau hauv lub xov tooj ntawm tes rau ntau tiam neeg yam tsis tua tus kab mob.
Phages muaj ntau yam kev siv hauv molecular biology. Lawv siv los kho cov kab mob pathogenic cov kab mob uas tiv taus cov tshuaj tua kab mob. Ntxiv mus, lawv tuaj yeem siv los txheeb xyuas cov kab mob tshwj xeeb hauv kev kuaj mob.
TMV yog dab tsi?
Tobacco Mosaic Virus (TMV) yog ib hom kab mob nroj tsuag uas kis tau tus tswv tsev Tobacco. Yog li ntawd, TMV yog cov kab mob luam yeeb. Ntxiv nrog rau kev haus luam yeeb, TMV tuaj yeem kis tau ntau yam ntawm cov nroj tsuag nrog rau ntau cov qoob loo, ornamentals thiab nroj tsuag. TMV yog ib qho ntawm cov kab mob uas tau kawm ntau tshaj plaws. Qhov tseeb, nws yog thawj tus kab mob uas tau txheeb pom. Raws li txoj cai, nws yog ib qho zoo-xav tau tus kab mob RNA ib leeg. Nws yog tus kab mob helical uas muaj 2130 subunits ntawm ib qho qauv protein uas muaj 157 amino acids hauv cov protein capsid.
Daim duab 02: Tobacco Mosaic Virus
TMV kis tau tus neeg kho tshuab los ntawm kev puas tsuaj nrog cov kua qaub. Cov tsos mob tseem ceeb ntawm tus kab mob TMV yog "mosaic" zoo li mottling thiab discoloration ntawm nplooj. TMV muaj feem cuam tshuam nrog txiv lws suav mosaic virus (ToMV). TMV nkag mus rau cov nroj tsuag los ntawm cov ntaub so ntswg raug mob. Kev vam meej TMV yuav tsum tau pib tsim thiab sib sau ua ke hauv cov hlwb invaded, intercellular txav, thiab kev thauj mus los. TMV tsuas yog nyob hauv cov hlwb xwb. Tab sis nws tuaj yeem muaj sia nyob hauv lub xeev dormant hauv cov ntaub so ntswg tuag tau ntau xyoo, khaws nws lub peev xwm los kis cov nroj tsuag loj hlob.
Tsis muaj tshuaj los kho TMV. Qee qhov kev coj ua xws li cog cov nroj tsuag tsis muaj kab mob, tshem tawm cov nroj tsuag, tshem tawm cov khib nyiab, pov tseg cov nroj tsuag muaj kab mob, tshuaj tua kab mob thiab nthuav tawm cov nroj tsuag los ntawm cov noob, thiab lwm yam, tuaj yeem zam kev kis kab mob TMV.
Dab tsi yog qhov zoo sib xws ntawm Bacteriophage thiab TMV?
- Bacteriophage thiab TMV yog tus kab mob.
- Lawv yog cov kab mob hauv nruab nrog cev.
- Ob leeg yog cov kab mob sib kis uas ua rau muaj kab mob.
- Lawv muaj cov protein capsid thiab nucleic acid genome.
- Lawv tsuas muaj nyob hauv cov hlwb xwb.
- Ob leeg bacteriophage thiab TMV yog hom tshwj xeeb.
Qhov txawv ntawm Bacteriophage thiab TMV yog dab tsi?
Bacteriophage yog cov kab mob kis tus kab mob thaum TMV yog cov kab mob nroj tsuag uas kis rau cov nroj tsuag haus luam yeeb. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm bacteriophage thiab TMV. Ntxiv mus, feem ntau cov kab mob bacteriophages muaj lub taub hau-tail qauv thaum TMV yog tus kab mob zoo li tus pas nrig. Yog li, qhov no yog lwm qhov sib txawv ntawm bacteriophage thiab TMV.
Cov hauv qab no qhia txog qhov sib txawv ntawm bacteriophage thiab TMV hauv daim ntawv teev npe.
Summary – Bacteriophage vs TMV
Bacteriophage yog tus kab mob uas kis tau thiab rov ua dua hauv cov kab mob xwb. TMV yog tus kab mob uas kis tau thiab rov ua dua hauv cov kab mob hauv cov kab mob luam yeeb thiab lwm cov nroj tsuag Solanaceae. Qhov no yog qhov sib txawv tseem ceeb ntawm bacteriophage thiab TMV. Feem ntau ntawm cov kab mob bacteriophages muaj lub taub hau, ob txhais ceg thiab tus Tsov tus tw thaum TMV yog tus kab mob zoo li tus pas nrig. Bacteriophages tuaj yeem muaj DNA lossis RNA genomes thaum TMV muaj ib leeg-stranded RNA genome. Yog li, qhov no yog cov ntsiab lus ntawm qhov sib txawv ntawm bacteriophage thiab TMV.
