Lub luag haujlwm tseem ceeb ntawm centromere yog muab lub hauv paus rau kev sib dhos ntawm kinetochore, uas yog cov protein complex tseem ceeb rau kev sib cais ntawm chromosomal thaum lub sij hawm mitosis. Hauv electron micrographs ntawm mitotic chromosomes, kinetochores tshwm sim raws li cov qauv platelike tsim los ntawm ob peb txheej (Daim duab 4).
Lub hom phiaj ntawm lub centromere yog dab tsi?
Centromeres ua lub luag haujlwm tseem ceeb hauv sib npaug chromosome cais los ntawm kev coj ua lub rooj sib txoos ntawm microtubule khi kinetochore thiab ua haujlwm ua qhov chaw sib koom ua ke ntawm tus muam chromatids.

Centromere ua lub luag haujlwm tseem ceeb hauv kev sib cais ntawm cov chromosome thaum lub sijhawm mitosis thiab meiosis hauv eukaryotic hlwb. Centromere muaj nuj nqi suav nrog tus muam chromatid adhesion thiab kev sib cais, microtubule txuas, chromosome txav, tsim ntawm heterochromatin thiab mitotic checkpoint tswj.
Lub luag haujlwm ntawm centromere quizlet yog dab tsi?
Lub centromere yog ib feem ntawm a chromosome uas txuas tus muam chromatids. Thaum lub sij hawm mitosis, spindle fibers txuas rau lub centromere ntawm lub kinetochore.
Lub luag haujlwm ntawm centromeres yog dab tsi lawv tseem ceeb hauv kev faib hluav taws xob li cas?
Lub luag haujlwm ntawm lub cev ntawm lub centromere yog los ua qhov chaw sib sau ua ke ntawm cov kinetochores - cov txheej txheem ntau cov protein ntau uas yogLub luag haujlwm rau cov xwm txheej tiag tiag ntawm kev sib cais ntawm chromosome- piv txwv li khi microtubules thiab teeb liab rau lub voj voog ntawm tes thaum txhua tus chromosomes tau txais yuav raug …
