Cov yam ntxwv ntawm bacteriophages

Cov nucleic acid tuaj yeem yog DNA los yog RNA thiab tej zaum yuav yog ob-stranded los yog ib leeg-stranded. Muaj peb hom qauv ntawm phage: lub taub hau icosahedral (20-sided) lub taub hau nrog tus Tsov tus tw, lub taub hau icosahedral tsis muaj tus Tsov tus tw, thiab daim ntawv filamentous.

Ib yam li ntawd ib tug yuav nug, dab tsi yog qhov chaw ntawm bacteriophage?

Cov tailed phages muaj peb loj cov khoom : lub capsid qhov twg cov genome tau ntim, tus Tsov tus tw uas ua haujlwm raws li cov yeeb nkab thaum kis kab mob kom ruaj ntseg hloov ntawm genome mus rau hauv lub xov tooj ntawm tes thiab cov nplaum tshwj xeeb (adsorption apparatus) ntawm qhov kawg ntawm tus Tsov tus tw uas yuav paub txog tus tswv cell thiab nkag mus. nws phab ntsa.

Kuj Paub, qhov ua haujlwm ntawm bacteriophage yog dab tsi? Bacteriophage enzymes rhuav tshem cov kab mob phab ntsa ntawm ob sab nraud thiab sab hauv los ntawm hydrolyzing carbohydrate thiab protein ntau cov khoom. Tag nrho cov no cov proteins tiv thaiv phage genetic khoom, ruaj ntseg txhaj tshuaj ntawm phage nucleic acid rau hauv cov kab mob ntawm tes, thiab txhawb phage propagation.

Tsis tas li ntawd, muaj pes tsawg tus bacteriophages muaj?

1031 cov kab mob bacteriophages

Yuav ua li cas bacteriophage replicate?

Bacteriophages , tseem hu ua phages, yog cov kab mob uas kis tau thiab rov ua dua tsuas yog nyob rau hauv cov kab mob hlwb. Thaum lub sij hawm lytic rov ua dua cycle, ib phage txuas mus rau tus kab mob uas raug tus kab mob, qhia nws cov genome rau hauv lub cell cytoplasm, thiab siv cov ribosomes ntawm tus tswv tsev los tsim nws cov proteins.
