Thaum anaphase 1, ob chromatids txav raws li ib chav tsev los ntawm txhua lub tetrads mus rau tus ncej ntawm spindle Lwm ob homologous chromatids txav mus rau lwm tus ncej. Lub homologous chromosomes tau sib cais tam sim no. Yog li hauv prophase, peb yuav pom ib nrab chromosome cais ntawm tus ncej.
Yuav ua li cas thaum anaphase 1 hauv meiosis?
Anaphase Kuv pib thaum homologous chromosomes cais Lub hnab ntawv nuclear hloov kho thiab nucleoli rov tshwm sim. Cov chromosomes coil nce, cov membrane nuclear pib tawg, thiab cov centrosomes pib sib nrug. Spindle fibers daim ntawv thiab tus muam chromatids dlhos mus rau txoj kab nruab nrab ntawm lub cell.
Yuav ua li cas hauv anaphase I ntawm meiosis 1 quizlet?
Yuav ua li cas thaum anaphase I ntawm meiosis? Homologous chromosomes cais tab sis tus muam chromatids tseem koom nrog ntawm lawv cov centromeres Meiosis ua rau muaj kev hloov pauv caj ces ntawm nws cov khoom lag luam. … -Cov khoom siv noob caj noob ces sib pauv ntawm homologous chromosomes hauv meiosis thaum hla dhau.
Qhov tshwm sim ntawm anaphase 1 yog dab tsi?
Anaphase I yog theem thib peb ntawm meiosis I thiab ua raws li prophase I thiab metaphase I. Qhov theem no yog tus cwj pwm los ntawm txav ntawm chromosomes mus rau ob tug ncej ntawm ib lub xovtooj meiotic ntawm ib microtubule network hu ua spindle apparatus. Cov txheej txheem no cais homologous chromosomes rau hauv ob pawg sib cais.
Lub ntsiab lus ntawm anaphase 1 yog dab tsi?
Nyob rau hauv anaphase kuv, cov khub homologous chromosomes yuav sib cais los ntawm ib leeg thiab txav mus rau sab nraud ntawm tes raws li lub kinetochore microtubules luv theem no pib sai li sai tau thaum homologous chromosomes pib. sib cais thiab xaus thaum cov chromosomes tuaj txog ntawm qhov kawg ntawm tes.
