Extranuclear qub txeeg qub teg los yog cytoplasmic keeb kwm yog kev sib kis ntawm cov noob uas tshwm sim sab nraum lub nucleus. Nws muaj nyob rau hauv feem ntau eukaryotes thiab feem ntau paub tias tshwm sim hauv cytoplasmic organelles xws li mitochondria thiab chloroplasts los yog los ntawm cellular parasites xws li kab mob los yog kab mob.
Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog cytoplasmic qub txeeg qub teg thiab piv txwv?
cytoplasmic keeb kwm Tsis yog Mendelian (extra-chromosomal) qub txeeg qub teg ntawm cov noob hauv cytoplasmic organelles. Piv txwv Ntawm cov organelles yog cov kab mob, mitochondria, thiab plastids.
Kuj Paub, dab tsi yog ntau yam yam ntxwv ntawm cytoplasmic qub txeeg qub teg? Yam ntxwv ntawm Cytoplasmic Inheritance : Cov cytoplasmic keeb kwm tuaj yeem kuaj tau los ntawm txoj kev tshwj xeeb. Ob txoj cai yog siv rau lawv qhov kev kuaj pom; ib qho tsis zoo thiab lwm qhov zoo. Cov noob nyob rau hauv cov kab mob diploid muaj nyob rau hauv khub thiab ob tug tswv cuab los yog lwm hom ntawm ib hom noob hu ua alleles.
Tom qab ntawd, ib tus tuaj yeem nug, puas muaj qhov sib txawv ntawm niam txiv cov txiaj ntsig thiab cytoplasmic qub txeeg qub teg?
Tus yuam sij qhov sib txawv ntawm cytoplasmic inheritance thiab caj ces niam txiv yog tias cytoplasmic keeb kwm tshwm sim vim cov ntaub ntawv caj ces khaws cia hauv cov noob ntawm qee cov organelles xws li mitochondria thiab chloroplasts tam sim no. hauv cytoplasm thaum caj ces niam txiv tshwm sim vim mRNA thiab cov protein tau txais
Leej twg leej niam leej txiv pab txhawb ntau dua hauv cytoplasmic qub txeeg qub teg?
Yog li cas cytoplasmic keeb kwm , nyias muaj nyias tej teebmeem. Qhov no feem ntau yog vim ntau kev pab ntawm cytoplasm mus rau zygote los ntawm poj niam niam txiv dua txiv neej niam txiv . Feem ntau ovum pab txhawb ntau cytoplasm mus rau zygote tshaj phev.

Dab tsi yog qhov txawv ntawm cov lus teb cytoplasmic thiab cov lus teb nuclear?
Dab tsi yog qhov txawv ntawm cov lus teb nuclear thiab cov lus teb cytoplasmic? Cov lus teb nuclear cuam tshuam nrog kev hloov pauv ntawm cov noob qhia, thaum cov lus teb cytoplasmic cuam tshuam nrog kev ua kom muaj enzyme lossis qhib ntawm ion channel
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
Hom kev hloov pauv txawv txawv li cas pom ntawm cov Islands tuaj?
Divergent evolution tshwm sim thaum ob hom sib txawv hloov pauv txawv ntawm ib tus poj koob yawm txwv. Speciation yog qhov tshwm sim ntawm kev hloov pauv hloov pauv thiab tshwm sim thaum ib hom sib txawv rau ntau hom xeeb leej xeeb ntxwv. Darwin's finches yog ib qho piv txwv ntawm qhov no
Yuav ua li cas koj pom tus qauv sib txawv ntawm qhov sib txawv?
Txhawm rau xam qhov sib txawv ntawm tus qauv, ntxiv tag nrho cov ntsiab lus ntawm cov ntaub ntawv thiab faib los ntawm tus lej ntawm cov ntaub ntawv cov ntsiab lus, suav qhov sib txawv ntawm txhua qhov chaw cov ntaub ntawv thiab tom qab ntawd nrhiav lub hauv paus square ntawm qhov sib txawv
Dab tsi yog cytoplasmic inheritance thiab piv txwv?
Qhov qub txeeg qub teg ntawm cov cim tswj los ntawm cov noob muaj nyob rau hauv lub cell cytoplasm es tsis yog los ntawm cov noob ntawm chromosomes nyob rau hauv lub cell nucleus. Ib qho piv txwv ntawm cytoplasmic qub txeeg qub tes yog tswj los ntawm mitochondrial noob (saib mitochondrion)
