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

Pob chromosomes kab hauv metaphase 1 lossis 2?
Metaphase II: Chromosomes kab ntawm metaphase phaj. Anaphase II: Muam chromatids cais mus rau qhov kawg ntawm lub cell. Telophase II: Kev tsim gametes tshiab yog haploid, thiab txhua chromosome tam sim no tsuas muaj ib chromatid xwb.
Chromosomes kab nyob qhov twg thaum lub sij hawm quizlet metaphase?
Tus khub chromosomes kab nrog rau txoj kab nruab nrab ntawm tes. Qhov no tshwm sim tsuas yog hauv metaphase I. Hauv metaphase ntawm mitosis thiab meiosis II, nws yog tus muam chromatids uas kab raws tus kab zauv ntawm lub cell.
hom chromosomes kab li cas thaum lub sijhawm metaphase I?
Metaphase I: Thaum lub sijhawm metaphase I, cov cuab yeej spindle tsim los ntawm qhov kawg ntawm tes. Lub spindle apparatus ces xa tawm spindle fibers mus txuas rau chromosomes. Txawm li cas los xij, txij li homologous chromosomesyog kab ntawm ib sab rau kev hla dhau, lawv tau tuav nruj ua ke.
Pob chromosomes kab nyob nruab nrab hauv metaphase kuv nkaus xwb?
Thaum lub sijhawm metaphase, chromosomes kab nyob rau hauv middle ntawm cell.
