The effect of aging on oocyte parthenogenetic development and the dynamic changes of microtubule during meiotic division 老化对卵母细胞孤雌发育和减数分裂期间微管动态变化的影响
In meiosis it is not until anaphase ii that the centromere divides , the chromatids being termed daughter chromosomes after separation 在减数分裂期间,直到分裂后期ii两条染色单体才随着着丝点的分裂而彼此分开。
Centromere the region of the chromosome that contains the kinetochore , the structure that becomes attached to the nuclear spindle during mitosis and meiosis 着丝粒:染色体上包含着丝点的区域,在细胞有丝分裂和减数分裂期间与纺锤体相整合的一种结构。
