Lub ntsiab qhov sib txawv ntawm homologous thiab non-homologous chromosomes yog li ntawd homologous chromosomes muaj alleles ntawm tib hom noob hauv tib loci whereas tsis yog homologous chromosomes muaj alleles ntawm txawv hom noob caj noob ces.
Kuj paub yog, dab tsi yog nonhomologous recombination?
Nonhomologous recombination (NHR) yog txoj hauv kev loj rau kev kho cov chromosomal ob-strand so hauv DNA ntawm somatic hlwb. Cov dej num enriched nyob rau hauv high-molecular-yuag recombination complex uas zoo nkaus li suav nrog thiab xav tau tib neeg homologous pairing protein HPP-1 nrog rau NHR ligase.
Tsis tas li ntawd, homologous recombination txhais li cas? Homologous recombination . Txhais . Homologous recombination yog kev sib pauv ntawm DNA strands ntawm zoo sib xws los yog zoo tib yam nucleotide sequence. Nws tuaj yeem siv los kho qhov yuam kev-dawb ntawm ob-strand DNA so thiab ua kom muaj qhov sib txawv ntawm gametes thaum lub sij hawm meiosis.
Ib yam li ntawd, nws raug nug, puas yog homologous recombination tib yam li hla dhau?
Homologous Recombination Homologous recombination yog hom caj ces recombination uas tshwm sim thaum lub sij hawm meiosis (kev tsim cov qe thiab cov phev hlwb). Hla mus ua rau muaj kev sib hloov ntawm cov khoom siv noob caj noob ces thiab yog ib qho tseem ceeb ntawm kev hloov caj ces pom ntawm cov xeeb ntxwv.
Tsis homologous txhais li cas?
Txhais ntawm nonhomologous .: ua tsis zoo li kev cai caj ces -siv ntawm chromosomes ntawm ib pawg uas muaj cov noob tsis muaj npe…

Dab tsi yog qhov txawv ntawm qhov pom tseeb qhov loj thiab qhov ntsuas qhov ntsuas qhov tseeb?
Dab tsi yog qhov txawv ntawm qhov pom tseeb thiab qhov tseeb? Pom meej qhov loj npaum li cas yog qhov ci ntawm lub hnub qub tshwm los ntawm lub ntiaj teb thiab nyob ntawm qhov ci thiab qhov deb ntawm lub hnub qub. Qhov loj npaum li cas yog qhov ci ntawm lub hnub qub yuav tshwm sim los ntawm tus qauv nyob deb
Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Dab tsi yog qhov sib txawv ntawm qhov sib txawv ntawm cov kab sib txuas thiab ntau qhov sib piv?
6. (2 lub cim) Qhov sib txawv ntawm cov kab sib txuas (kev sib piv) thiab ntau qhov sib piv yog dab tsi? Cov kab sib xyaw ua ke yog npaj sib piv; uas yog, tshwj xeeb txhais tau tias yog ua ke nyob rau hauv ntau txoj kev thiab contrasted nrog rau lwm yam kev sib txuas ntawm txhais tau tias
Dab tsi yog qhov txawv ntawm instantaneous thiab nruab nrab ceev dab tsi yog qhov piv txwv loj tshaj ntawm kev ceev ceev?
Qhov nruab nrab ceev yog qhov ceev nruab nrab ntawm lub sijhawm. Instantaneous ceev yuav yog qhov ceev txhua qhov muab tam sim ntawd hauv lub sijhawm ntawd, ntsuas nrog lub ntsuas ntsuas lub sijhawm
Dab tsi yog qhov txawv ntawm microevolution thiab macroevolution Dab tsi yog qee qhov piv txwv ntawm txhua tus?
Microevolution vs. Macroevolution. Piv txwv ntawm cov kev hloov microevolutionary no yuav suav nrog kev hloov ntawm hom xim lossis loj. Macroevolution, piv txwv li, yog siv los hais txog kev hloov pauv ntawm cov kab mob uas tseem ceeb txaus uas, dhau sijhawm, cov kab mob tshiab yuav raug suav tias yog hom tshiab nkaus xwb
