Cov 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 hauv cell nucleus. Ib piv txwv ntawm cytoplasmic keeb kwm yog tswj los ntawm mitochondrial noob (saib mitochondrion).
Ib yam li ntawd, koj tuaj yeem nug, koj txhais li cas los ntawm cytoplasmic qub txeeg qub teg?
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.
Tsis tas li ntawd, Biparental qub txeeg qub teg yog dab tsi? biparental qub txeeg qub teg . (2) Ib hom extranuclear qub txeeg qub teg , nyob rau hauv uas ob niam txiv pab txhawb organellar DNA rau progeny, raws li tshwm sim nyob rau hauv biparental mitochondrial qub txeeg qub teg nyob rau hauv Saccharomyces cerevisiae (ib tug poov xab).
Kuj paub, dab tsi yog Extrachromosomal qub txeeg qub teg piav nrog piv txwv?
Extrachromosomal Inheritance . Mitochondrial qub txeeg qub teg yog tus qauv uas tsis yog-Mendelian uas kis tus kab mob tshwj xeeb ntawm cov poj niam thiab koom nrog qub txeeg qub teg ntawm mutant mitochondrial DNA rau cov xeeb ntxwv. Los ntawm: Cardiac Electrophysiology: Los Ntawm Cell mus rau Bedside (Seventh Edition), 2018.
Leej twg nrhiav tau cytoplasmic qub txeeg qub teg?
Pov thawj rau cytoplasmic keeb kwm thawj zaug tau tshaj tawm los ntawm Correns hauv Mirabilis jalapa thiab Bar hauv Pelargonium zonule hauv xyoo 1908. Rhoades tau piav qhia cytoplasmic txiv neej sterility nyob rau hauv pob kws nyob rau hauv 1933. Nyob rau hauv 1943, Sonneborn nrhiav pom kappa hais nyob rau hauv Paramoecium thiab piav txog nws cytoplasmic keeb kwm.

Yam ua piv txwv piv txwv li cas?
Ib khub xaj yog ib khub ntawm tus lej hauv ib qho kev txiav txim. Piv txwv li, (1, 2) thiab (- 4, 12) raug txiav ua khub. Qhov kev txiav txim ntawm ob tus lej tseem ceeb: (1, 2) tsis sib npaug rau (2, 1) -- (1, 2) ≠ (2, 1)
Dab tsi yog qhov sib piv thiab piv txwv?
Inverse proportion. Inverse proportions tshwm sim thaum ib tus nqi nce thiab qhov txo qis. Piv txwv li, ntau tus neeg ua haujlwm ntawm txoj haujlwm yuav txo lub sijhawm los ua kom tiav cov haujlwm. Lawv yog inversely proportional
Dab tsi yog txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms
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
