Thaum lub sijhawm metaphase, lub xov tooj ntawm tes chromosomes kho lawv tus kheej nyob rau hauv nruab nrab ntawm lub xovtooj los ntawm hom cellular "tug of war." Cov chromosomes, uas tau hloov dua tshiab thiab tseem koom nrog ntawm lub hauv paus ntsiab lus hu ua centromere, hu ua tus muam chromatids viv ncaus chromatids Tus muam chromatids yog khub ntawm cov ntawv luam zoo tib yam ntawm DNA koom ntawm qhov taw teshu ua chaw nyob. Thaum lub sij hawm anaphase, txhua khub ntawm chromosomes tau muab cais ua ob qho tib si, chromosomes ywj siab. Cov chromosomes tau sib cais los ntawm cov qauv hu ua mitotic spindle. https://www.nature.com › scitable › definition › anaphase-179

Chromosomes kab nyob qhov twg thaum lub sijhawm metaphase?
Metaphase: Thaum lub sijhawm metaphase, txhua tus ntawm 46 chromosomes kab nrog rau qhov chaw ntawm lub xovtooj ntawm lub phaj metaphase.
Vim li cas cov chromosomes yuav tsum ua kom haum ntawm lub phaj metaphase?
doi.org/10.1083/jcb.201807228) qhia tias chromosome alignment ensures mitotic fidelity by promoting interchromosomal compaction while anaphase. Thaum lub sij hawm mitosis, chromosomes ua ke ntawm spindle equator los tsim ib lub phaj metaphase.
Thaum lub sijhawm twg ntawm mitosis ua cov chromosomes sib dhos ntawm cov phaj metaphase?
Metaphase follows prophase. Thaum metaphase, chromosomesnyob rau hauv nruab nrab ntawm lub cell ntawm lub equatorial phaj thiab spindle fibers txuas mus rau lub centromeres ntawm cov chromosomes. Anaphase koom nrog kev thim rov qab ntawm spindle fibers thiab kev sib cais rau tus muam chromatids.
Cov kauj ruam ntawm metaphase yog dab tsi?
Metaphase. Chromosomes kab ntawm lub phaj metaphase, nyob rau hauv nro los ntawm mitotic spindle. Ob tug viv ncaus chromatids ntawm txhua tus chromosome raug ntes los ntawm microtubules los ntawm cov ncej spindle. Hauv metaphase, tus ntxaiv tau ntes tag nrho cov chromosomes thiab muab lawv tso rau ntawm nruab nrab ntawm tes, npaj los faib.
