Generalized transduction yog kho los ntawm lytic phages qhov twg ib ntu DNA tuaj yeem raug xa mus los ntawm tus kab mob thiab tsis tuaj yeem koom ua ke ntu rau cov kab mob chromosome. thaum tshwj xeeb transduction yog ib qho txheej txheem uas ib feem ntawm cov kab mob DNA ntim rau hauv lub taub hau phage uas kis mus rau lwm cov kab mob.

Hauv txoj kev no, kev hloov pauv dav dav sib txawv li cas los ntawm kev hloov pauv tshwj xeeb?

Muaj ob hom kev hloov pauv : generalized thiab tshwj xeeb . Hauv generalized transduction , cov kab mob bacteriophages tuaj yeem khaws ib feem ntawm tus tswv tsev genome. Nyob rau hauv sib piv, nrog tshwj xeeb transduction , cov kab mob bacteriophages khaws tsuas yog qee feem ntawm tus tswv tsev DNA.

Qhov thib ob, qhov txawv ntawm transfection thiab transduction yog dab tsi? Kev hloov pauv yog cov txheej txheem ntawm kev qhia nucleic acids rau hauv cov hlwb los ntawm txoj kev tsis yog kab mob. Kev hloov pauv yog cov txheej txheem uas txawv teb chaws DNA tau nkag mus rau hauv lwm lub cell ntawm tus kab mob vector. Ib txoj hauv kev los xyuas kom meej tias cov khoom siv caj ces tau ua tiav hauv cov hlwb yog ntsuas cov protein qhia.

Tsis tas li ntawd, qhov txawv ntawm phage hloov dua siab tshiab thiab tshwj xeeb transduction yog dab tsi?

Nyeem ntxiv. Kev hloov pauv yog tus txheej txheem uas cov kab mob DNA kis los ntawm bacteriophages (cov kab mob) mus rau hauv cov kab mob genome. Muaj ob theem ntawm kev hloov pauv - lytic thiab lysogenic theem. Tshwj xeeb traduction: feem ntau tshwm sim thaum lub phage " txiav txim siab" tawm ntawm lysogenic theem.

Transduction hauv biology yog dab tsi?

Kev hloov pauv , cov txheej txheem ntawm kev sib txuas ntawm cov kab mob hauv cov kab mob uas cov noob ntawm lub cell (ib kab mob) tau muab tso rau hauv cov kab mob ntawm cov kab mob (bacteriophage) thiab tom qab ntawd nqa mus rau lwm lub xov tooj ntawm tes thaum bacteriophage pib ua lwm lub voj voog ntawm kev kis kab mob.
