Centrosome yog thaj chaw uas cov ntxaiv fibers pib rau daim ntawv. Cov centrosome yog tsim nyog rau mitosis vim tsis muaj centrosome , spindle fibers yuav tsis tsim, yog li ntawd yuav tsis muaj ib yam dab tsi los rub tus viv ncaus chromtids sib nrug rau cov lus qhia rov qab thiab mob mitosis yuav tsis tshwm sim zoo.
Thiaj li, lub luag haujlwm ntawm centrosome hauv mitosis yog dab tsi?
Centrosomes yog cov qauv pom hauv cov hlwb. Lawv yog tsim los ntawm ob centrioles. Centrioles yog microtubule rings. Lub hom phiaj tseem ceeb ntawm a centrosome yog los npaj microtubules thiab muab cov qauv rau ntawm tes, nrog rau kev ua haujlwm kom rub chromatids sib nrug thaum sib faib ntawm tes.
Lub luag haujlwm ntawm Centriole hauv kev faib cell yog dab tsi? Muaj ob lub ntsiab kev ua haujlwm ntawm centrioles uas peb yuav tsom ntsoov rau. Lub ntsiab muaj nuj nqi ntawm centriole yog pab nrog cell faib u zoov hlwb . Cov cov centrioles pab tsim cov spindle fibers uas cais cov chromosomes thaum cell faib ( mob mitosis ). Cilia thiab flagella pab ntawm tes txav.
Ib yam nkaus, puas xav tau centrosomes rau mitosis?
Centrosomes tsis yog xav tau rau cov mob mitosis tshwm sim. Thaum lub centrosomes irradiated los ntawm laser, mob mitosis ua haujlwm nrog ntxaiv ib txwm. Hauv qhov tsis muaj centrosome , cov microtubules ntawm ntxaiv tau tsom mus rau tsim ib hom bipolar spindle. Ntau lub hlwb tuaj yeem ua tiav interphase yam tsis muaj centrosomes.
Yuav ua li cas yog tias tsis muaj Centrioles?
Tsis muaj centrioles , cov cell organelles yuav tsis nyob hauv lawv qhov chaw zoo, thiab microtubules yuav tsis tuaj yeem ua haujlwm tau zoo, uas yuav tawm hauv hlwb tsis txhawb thiab lav kom poob lawv duab Tsis muaj ribosomes los tsim cov proteins, cov hlwb tsuas yog tsis tuaj yeem ua haujlwm zoo.
