Mitochondria yog tus kheej-replicating organellesuas tshwm sim nyob rau hauv ntau tus lej, duab, thiab qhov ntau thiab tsawg hauv cytoplasm ntawm tag nrho cov hlwb eukaryotic. Mitochondria muaj lawv tus kheej genome uas yog cais thiab txawv ntawm cov genome ntawm ib lub xovtooj ntawm tes. … Lawv yog lub zog ntawm lub cell.
Vim li cas mitochondria hu ua nws tus kheej?
Cell organelles uas muaj lawv tus kheej DNA thiab rov ua dua ntawm nws tus kheej ntawm lub nucleus tau hais tias yog ib nrab-autonomous. Mitochondria muaj lawv tus kheej DNA uas tuaj yeem luam tawm ntawm nws tus kheej. … Cov organelles muaj lawv tus kheej ribosomes, hu ua mitoribosomes.
Yuav ua li cas mitochondria duplicate?
Mitochondrial DNA yog replicated los ntawm DNA polymerase gamma complexuas yog tsim los ntawm 140 kDa catalytic DNA polymerase encoded los ntawm POLG noob thiab ob 55 kDa accessory subunits encoded los ntawm POLG2 noob. Lub tshuab replisome yog tsim los ntawm DNA polymerase, TWINKLE thiab mitochondrial SSB proteins.
YDo mitochondria rov ua dua hauv mitosis?
