Qhov txawv ntawm T2 thiab T4 bacteriophage yog tias hauv T2 bacteriophage, enzyme DNA Topo II yog coded los ntawm ob lub noob 39 thiab 60m, thaum nyob rau hauv T4 bacteriophage, cov enzyme no coded los ntawm peb noob 39, 60, thiab 52.
Bacteriophage yog ib hom kab mob uas kis kab mob. Bacteriophages yog cov kab mob noj vim lawv rhuav tshem cov hlwb ib zaug. Muaj ntau hom bacteriophages nrog rau kev siv morphology thiab nucleic acid. T2 bacteriophage thiab T4 bacteriophage yog ob hom. Ob hom kab mob thiab tua Escherichia coli.
T2 Bacteriophage yog dab tsi?
T2 bacteriophage yog tus kab mob uas kis tau thiab tua E.coli ua. Nws yog hu ua enterobacteria-phage T2. Bacteriophage T2 belongs rau phylum Uroviricota, tsev neeg Myoviridae, genus Tequatrovirus thiab hom Escherichia virus T4. Lub genome ntawm T2 bacteriophage muaj linear ob-stranded DNA. Qhov kawg ntawm DNA strands muaj kev rov ua dua. T2 bacteriophage muaj phage enzymes encoded los ntawm ob genes 39 thiab 60. Cov 39 protein muaj ATPase kev ua, thiab 60 muaj ib tug complex tsim muaj nuj nqi.
Daim duab 01: Myoviridae Bacteriophage 2
T2 bacteriophage txuas rau saum npoo ntawm cov kab mob los ntawm cov proteins lossis tail fibers thiab txhaj nws cov khoom siv caj ces (xws li DNA lossis RNA) rau hauv lub cell. Cov khoom siv tshuaj tua kab mob cuam tshuam nrog cov kab mob cell qauv thiab tshuab. Nws siv cov kab mob ribosomes rau replicate thiab synthesize viral cellular Cheebtsam xws li viral proteins. Yog li ntawd, T2 bacteriophages tshiab pib los ntawm cov kab mob uas muaj kab mob thiab ua lub luag haujlwm rau lysis ntawm cov kab mob hlwb thaum tso cov kab mob tshiab. Tshiab T2 macrophages txuas ntxiv cov kab mob ntawm cov kab mob tshiab.
T4 Bacteriophage yog dab tsi?
T4 bacteriophage yog tus kab mob uas kis tau E.coli thiab tua cov kab mob thaum kawg. Nws yog lub npe hu ua Escherichia virus T4. T4 bacteriophage yog ib tug kab mob DNA ob leeg. Nws belongs rau tsev neeg Myoviridae thiab sub-tsev neeg Tevenviridae. T4 bacteriophage mus dhau lub voj voog lytic tab sis tsis yog lub voj voog lysogenic. Qhov ob-stranded DNA ntawm T4 bacteriophage yog hais txog 169 kbp ntev. Nws encodes 289 proteins. Lub genome ntawm T4 yog terminally redundant thiab muaj eukaryotic zoo sib xws intron sequences.
Daim duab 02: Bacteriophage T4
Piv rau lwm hom kab mob bacteriophages, T4 bacteriophage yog ib tus kab mob loj loj nrog qhov ntev ntawm 90 nm dav thiab 200 nm ntev. Tus Tsov tus tw ntawm T4 bacteriophage yog hollow thiab kis cov nucleic acid rau cov kab mob kis thaum txuas. Tus Tsov tus tw yog ib tug complex qauv nyob rau hauv T4 bacteriophages nrog ntau cov proteins rau kev txuas thiab kev ua haujlwm. T4 bacteriophage muaj 3 lub noob rau encode kab mob proteins. Lawv yog noob 39, 60, thiab 52.
Dab tsi zoo sib xws ntawm T2 thiab T4 Bacteriophage?
- Ob leeg yog tus kab mob uas kis tus kab mob coli.
- Lawv muaj ob txoj hlua DNA.
- Ob leeg T2 thiab T4 bacteriophages tau dhau lub voj voog lytic ua rau cov kab mob tuag.
- Lawv nyiag cov kab mob cell mechanism los tsim cov kab mob kis.
Qhov txawv ntawm T2 thiab T4 Bacteriophage yog dab tsi?
T2 bacteriophage muaj ob lub noob 39 thiab 60, kom code DNA Topo II enzyme, thaum T4 bacteriophage muaj peb noob 39, 60, thiab 52 rau code DNA Topo II enzyme. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm T2 thiab T4 bacteriophage. Ntxiv mus, tus Tsov tus tw ntawm T2 bacteriophage tsis nyuaj thaum piv rau tus Tsov tus tw ntawm T4 bacteriophage.
Cov hauv qab no qhia txog qhov sib txawv ntawm T2 thiab T4 bacteriophage hauv daim ntawv teev npe rau ib sab ntawm kev sib piv.
Summary – T2 vs T4 Bacteriophage
Bacteriophage yog ib hom kab mob uas kis kab mob. Thaum kis tus kab mob, tus kab mob bacteriophage txuas mus rau cov kab mob uas raug cuam tshuam, tso cov khoom siv caj ces, thiab kis mus rau tus tswv tsev cell. T2 bacteriophage thiab T4 bacteriophage yog ob hom. Ob hom kab mob thiab tua Escherichia coli. T2 bacteriophage muaj phage enzymes encoded los ntawm ob genes 39 thiab 60. T4 bacteriophage muaj 3 noob rau encode kab mob proteins. Lawv yog cov noob 39, 60, thiab 52. Tus Tsov tus tw ntawm T2 bacteriophage tsis nyuaj thaum piv rau tus Tsov tus tw ntawm T4 bacteriophage. Ob leeg T2 thiab T4 bacteriophages tau dhau lub voj voog lytic ua rau cov kab mob cell tuag. Yog li, qhov no yog cov ntsiab lus ntawm qhov sib txawv ntawm T2 thiab T4 bacteriophage.
