constrosomes muaj ntawm ob centriolescov ces kaum, thiab ib puag ncig ntawm cov protein uas tau hais tseg cov khoom siv pricentriolar (PCM). PCM muaj cov protein ua lub luag haujlwm rau microtubule nucleation thiab anchoring - suav nrog γ-tubulin, pericentrin thiab ninein.
Puas yog centrosome muaj centrioles?
Hauv lub xovtooj ntawm tes, lub centrosome yog cov qauv uas tsim cov microtubules thaum lub sijhawm cell faib. Txhua lub centrosome muaj "paired chim-zoo li tus organelles" hu ua centrioles thiab "huab" ntawm cov proteins hu ua cov khoom siv pericentriolar, los yog PCM.
Centrosome muaj dab tsi?
Zaj. Lub centrosome muaj ob lub microtubule-raws li centrioles (ib leej niam thiab tus ntxhais centriole)uas txawv ntawm hnub nyoog thiab cov qauv zoo sib xws tab sis tsis zoo ib yam. Lub centrosome yog qhov loj microtubule-organizing chaw nyob rau hauv lub cell.
Cov hlwb twg muaj centrioles?
Centrioles yog khub thoob lub cev zoo li lub cev nyob rau hauv lub cytoplasm ntawm tsiaj hlwb ze ntawm lub hnab ntawv nuclear.
Puas centrioles tig mus ua centrosomes?
Peb cov txiaj ntsig tau tshaj tawm tias a Plk1-dependent hloov kho, uas tshwm sim nyob rau hauv thaum ntxov mitosis, yuav tsum tau hloov centrioles rau centrosomes / MTOCs thaum lig mitosis (Fig. 7). … Qhov tseem ceeb, cov centrioles tsis hloov pauv yuav tsum koom nrog MTOC-tswj centrioles yog tias lawv yuav tsum tau muab cais kom raug thaum lub sij hawm mitosis (Fig. 7).
