Bacteriophages paub lawv host kab mob los ntawm kev txuas rau qhov tshwj xeeb cell nto receptors. Hauv cov kauj ruam tom ntej, lawv txhaj lawv DNA lossis RNA rau hauv kab mob mus reprogram cov cell . Tam sim no kev tsim cov phage tshiab pib. Los ntawm txoj kev no lawv kis tau los ntawm cov kab mob , thaum tus tswv cell ntau ntau.

Tom qab ntawd, ib tug kuj yuav nug, yuav ua li cas bacteriophage txuas mus rau cov kab mob ntawm tes?

Kom kis tau kab mob , feem ntau cov kab mob bacteriophages ntiav ib tug 'tail' uas stab thiab pierces lub cov kab mob daim nyias nyias tso cai rau tus kab mob cov khoom siv caj ces hla mus. Thaum tus kab mob txuas rau cov kab mob nto, lub sheath cog lus thiab tsav lub raj los ntawm nws.

Kuj Paub, cov kab mob bacteriophages tuaj yeem kis rau tib neeg lub hlwb? Txawm tias cov kab mob bacteriophages ua tsis tau kis tau thiab replicate hauv tib neeg hlwb , lawv yog ib feem tseem ceeb ntawm cov tib neeg microbiome thiab tus neeg nruab nrab tseem ceeb ntawm kev sib pauv caj ces ntawm cov kab mob pathogenic thiab cov kab mob uas tsis yog-pathogenic[5][6].

Kuj nug, dab tsi yog phage txhaj rau hauv cov kab mob ntawm tes?

Cov theem ntawm lub voj voog lytic yog: Txuas: Proteins hauv lub "tail" ntawm lub phage khi rau ib tug tshwj xeeb receptor ( hauv rooj plaub no, tus neeg thauj khoom qab zib) ntawm qhov saum npoo ntawm kab mob cell . Nkag mus: The phage txhaj nws ob-stranded DNA genome rau hauv lub cytoplasm ntawm lub kab mob.

Yuav ua li cas tshwm sim thaum bacteriophage kis mus rau ib tug kab mob cell?

Nws txhaj tshuaj genetic info rau hauv nws. Cov noob kab mob ua rau tsim ntau yam tshiab cov kab mob bacteriophages , thiab lawv maj mam rhuav tshem nws. Cov khoom siv noob caj noob ces kab mob bacteriophage yog DNA, tsis yog protein.
