Nyob ntawd yog peb lub ntsiab txoj kev uas genetic recombination tshwm sim hauv kab mob , thawj ntawm uas yog hu ua transformation. Qhov no yog thaum ib daim DNA pub dawb los ntawm tus neeg tau txais kab mob.
Ib yam li ntawd, muaj pes tsawg hom recombination muaj?
Tsawg kawg yog plaub hom ntawm naturally tshwm sim recombination tau raug txheeb xyuas hauv cov kab mob uas muaj sia nyob (Daim duab 8.1). General los yog homologous recombination tshwm sim ntawm DNA molecules ntawm ib ntu zoo sib xws, xws li homologous chromosomes hauv cov kab mob diploid.
Tsis tas li ntawd, peb txoj hauv kev ntawm kev sib txuas ntawm caj ces hauv cov kab mob yog dab tsi? Txawm li cas los xij, cov kab mob tau pom txoj hauv kev los ua kom lawv cov caj ces muaj ntau haiv neeg los ntawm peb txoj kev sib txuas ua ke: kev hloov pauv, hloov pauv thiab sib txuas.
- Genetic Recombination yog dab tsi?
- Kev hloov pauv.
- Kev hloov pauv.
- Conjugation.
Kuj nug, peb hom recombination yog dab tsi?
Muaj peb hom recombination ; Radiative, Shockley-Read-Hall, thiab Auger.
Dab tsi yog txoj kev sib txawv ntawm genetic recombination hauv cov kab mob?
Cov txheej txheem no tshwm sim hauv peb lub ntsiab txoj kev : Transformation, uptake ntawm exogenous DNA los ntawm ib puag ncig ib puag ncig. Transduction, tus kab mob-mediated hloov ntawm DNA nruab nrab kab mob . Conjugation, kev hloov ntawm DNA los ntawm ib kab mob mus rau lwm qhov ntawm kev sib cuag ntawm tes-rau-cell.

Muaj pes tsawg txoj kev nyob nruab nrab ntawm ob txoj kab ntsug?
Qhov no muab peb txoj hauv kev ntawm qhov chaw (A) thiab qhov chaw (E) vertex
Muaj pes tsawg qhov kev zam rau tus qauv electron configurations muaj nyob rau hauv D block?
ob Ntawm no, cov ntsiab lus twg yog kev zam rau Aufbau txoj cai? Piv txwv li, ruthenium, rhodium, nyiaj thiab platinum yog tag nrho kev zam rau Aufbau txoj cai vim yog sau los yog ib nrab puv subshells. Ib sab saum toj no, yog vim li cas electron configuration rau tooj liab 1s22s22p63s23p63d104s1 es tsis txhob 1s22s22p63s23p63d94s2?
Dab tsi yog cov kab mob piav qhia cov kab mob ntawm tes hauv kev nthuav dav?
Cov kab mob yog cov prokaryotes, tsis muaj cov nuclei zoo thiab cov kab mob sib txuas ua ke, thiab nrog cov chromosomes tsim los ntawm ib lub voj voog DNA kaw. Lawv tuaj nyob rau hauv ntau yam duab thiab ntau thiab tsawg, los ntawm feeb spheres, cylinders thiab kauv threads, rau flagellated rods, thiab filamentous chains
