Thaum lub sijhawm metaphase, lub kinetochore microtubules rub tus muam chromatids viv ncaus chromatids Tus viv ncaus chromatids yog khub ntawm cov ntawv luam zoo sib xws ntawm DNA koom nrog ntawm qhov taw teshu ua centromere. 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
anaphase | Kawm Science ntawm Scitable - Nature
rov qab mus txog rau thaum lawv ua raws txoj kab nruab nrab ntawm lub xovtooj, hu ua equatorial dav hlau. Muaj qhov chaw kuaj xyuas tseem ceeb hauv nruab nrab ntawm mitosis, hu ua metaphase checkpoint, thaum lub sij hawm lub cell kom paub meej tias nws npaj txhij los faib.
Yuav ua li cas hauv metaphase ntawm mitosis yooj yim?
Metaphase. Chromosomes kab nyob rau 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 lub xovtooj, npaj los faib.
Yuav ua li cas thaum lub sijhawm metaphase hauv meiosis?
Nyob rau hauv metaphase I, cov khub homologous ntawm chromosomes dlhos rau ntawm ob sab ntawm lub phaj equatorial. … Txhua tus ntxhais cell yog haploid thiab tsuas muaj ib pawg chromosomes xwb, los yog ib nrab ntawm tag nrho cov chromosomes ntawm thawj cell. Meiosis II yog mitotic divisionntawm txhua lub hlwb haploid tsim nyob rau hauv meiosis I.
Yuav ua li cas thaum lub sijhawm metaphase thiab anaphase ntawm mitosis?
Dab tsi tshwm sim thaum Metaphase thiab Anaphase? Raws li prometaphase xaus thiab metaphase pib, cov chromosomes ua raws li cov xov tooj ntawm tes. … Metaphase ua rau anaphase, thaum lub sij hawm uas txhua tus chromosome tus muam chromatids cais thiab txav mus rau opposite ncej ntawm lub cell.
Yuav ua li cas hauv metaphase ntawm mitosis thiab meiosis?
Metaphase yog ib theem ntawm lub voj voog ntawm tes uas tshwm sim hauv ob qho tib si mitosis thiab meiosis cell division processes. Thaum lub sij hawm metaphase nyob rau hauv mitosis thiab meiosis, cov chromosomes condense thiab lawv pom thiab paub qhov txawv thaum lub sij hawm kev sib raug zoo ntawm qhov chaw ntawm lub cell faib, tsim ib tug metaphase phaj nyob rau hauv nruab nrab ntawm lub cell.
