Lysogeny, hom lub neej voj voog uas tshwm sim thaum tus kab mob bacteriophage kis qee yam kab mob. Hauv cov txheej txheem no, cov genome (kev sau cov noob nyob rau hauv nucleic acid core ntawm tus kab mob) ntawm cov kab mob bacteriophage ruaj khov ua ke rau hauv chromosome ntawm tus kab mob tus tswv thiab rov ua dua hauv kev hais kwv txhiaj nrog nws.
Phage ua rau lysogeny?
Thaum lub sijhawm induction, prophage DNA yog excised los ntawm cov kab mob genome thiab tau sau thiab txhais ua cov txheej txheem rau tus kab mob thiab tswj kev loj hlob lytic. Tus qauv kab mob rau kev kawm lysogeny yog lambda phage.
Cov xwm txheej twg los tsim kom muaj Lysogen ua tiav?
Tsim kom muaj lysogeny koom nrog qhov kev txiav txim siab lysis-lysogeny, uas tshwm sim 10-15 feeb tom qab pib kis tus kab mob nrog phage λ raws li tus qauv kuaj mob. Lysogenic cycles tshwm sim thaum qib λ CII protein ntau, qhov lytic cycles tshwm sim thaum cov qib CII protein tsawg.
Dab tsi ua rau lub voj voog lysogenic?
Nyob rau hauv lub voj voog lysogenic, phage DNA tau muab tso rau hauv tus tswv tsev genome, uas nws tau dhau mus rau tiam tom ntej. Kev ntxhov siab ib puag ncig xws li kev tshaib plab lossis raug tshuaj lomtuaj yeem ua rau prophage rau excise thiab nkag mus rau lub voj voog lytic.
Dab tsi ua rau cov kab mob bacteriophage λ mus rau lysis lossis lysogeny?
Hauv λ, 'kev txiav txim siab' nkag mus rau lysogeny yog tsav los ntawm geneticcompatibility (piv txwv li, host attB integration sites), host physiological state (piv txwv li, nutrient depletion nce lysogeny) thiab phage ntom (piv txwv li, siab dua MOIs nce lysogeny) (Casjens thiab Hendrix, 2015).
