Nucleolus daim nyias nyias pib tawg nyob rau hauv early prophase. Lub cytoskeleton ntawm lub cev, Golgi complex, ER, thiab lwm yam, ploj mus. Lub nucleus thiab cell ua spheroid thaum lub sij hawm ntxov prophase ntawm mitosis.
theem twg ntawm mitosis puas lub nucleolus thiab ER pib ploj?
Prophase yog thawj theem ntawm mitosis thiab meiosis ntawm cell division. Thaum interphase, ob daim ntawv theej ntawm cov chromosomes zoo tib yam yog rov ua dua ua tus muam chromatids. Tom qab ntawd lawv nkag mus rau prophase thiab pib chromosome condensation thiab ploj ntawm nucleolus nrog rau endoplasmic reticulum.
Nyob rau theem twg mitosis puas lub nucleus ploj?
Thaum prophase, lub nucleus ploj mus, spindle fibers tsim, thiab DNA condenses rau hauv chromosomes (tus muam chromatids). Thaum lub sij hawm metaphase, tus viv ncaus chromatids ua raws txoj kab nruab nrab ntawm lub cell los ntawm kev txuas lawv cov centromeres rau cov spindle fibers.
Nyob rau theem twg ntawm mitosis yog cov nucleolus pom zoo?
In prophase, cov nucleolus ploj mus thiab chromosomes condense thiab pom. Hauv prometaphase, kinetochores tshwm sim ntawm centromeres thiab mitotic spindle microtubules txuas rau kinetochores. Hauv metaphase, chromosomes yog lined thiab txhua tus viv ncaus chromatid txuas nrog spindle fiber.
Nyob rau theem twg ntawm prophase 1 ua lub nucleolusploj?
Thaum ntxov Yaj Saub. Lub mitotic spindle pib tsim, cov chromosomes pib condense, thiab cov nucleolus ploj. Thaum ntxov prophase, lub xovtooj ntawm tes pib rhuav tshem qee cov qauv thiab tsim lwm tus, teeb tsa theem rau kev faib cov chromosomes.
