Feem ntau, "lub voj voog lytic" tshwm sim, qhov twg lambda DNA rov ua dua thiab phage tshiabcov khoom raug tsim tawm hauv lub xovtooj. Qhov no yog ua raws li cell lysis, tso cov ntsiab lus ntawm tes, suav nrog cov virions uas tau sib sau ua ke, rau hauv ib puag ncig.
Yuav ua li cas thaum lub voj voog lytic ntawm phage replication?
Thaum lub sijhawm lytic voj voog ntawm tus kab mob rov ua dua, tus kab mob hijacks tus tswv tsev cell, degrades tus tswv chromosome, thiab ua rau ntau tus kab mob genomes. Raws li nws sib sau thiab ntim DNA rau hauv lub taub hau phage, ntim qee zaus ua yuam kev.
Qhov tshwm sim ntawm lub voj voog lytic ntawm bacteriophage λ yog dab tsi?
Lub voj voog lytic tshwm sim hauv kev puas tsuaj ntawm cov kab mob thiab nws daim nyias nyias. Bacteriophages uas tsuas yog siv lub voj voog lytic hu ua virulent phages (piv txwv li temperate phages).
lambda phage replication li cas?
Viral replication machinery replicates lambda genome los ntawm dov lub voj voog, tsim cov kab sib txuas genome concatemersTerminase khi rau 5 'genome concatemers, thiab los ntawm khi rau khoob procapsids. Viral genomic DNA tau ntim rau hauv lub zog nyob ntawm tus yam ntxwv, thiab lub terminase cleaves cos site ntawm qhov kawg ntawm genome.
Lub luag haujlwm ntawm lambda repressor hauv lytic voj voog yog dab tsi?
Taw qhia. cI yog ib tug transcription inhibitor ntawm bacteriophage Lambda. Kuj tseem hu ua Lambda Repressor, cI yog lub luag haujlwm rau kev tswj hwm lub neej lysogenic ntawm phage Lambda Qhov no tau ua tiav thaum ob tus neeg tawm tsam dimers khi kev koom tes rau cov chaw ua haujlwm nyob ib sab ntawm DNA.
