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.
