查询词典 chromatid

In evl-14 mutant animals, synaptonemal complexes were detectable at the pachytene arrest, but more than the usual six DAPI-staining positive structures were seen in diakinesis, suggesting that EVL-14/PDS-5 is important for the maintenance of sister chromatid cohesion in the late prophase.

这一结果提示EVL-14／PDS-5对于在减数分裂的晚前期维持姐妹染色单体粘连是十分重要的。

Genes important for male gametogenesis involved in highly con-served landmark events such as meiotic recombination, formation of the synaptonemal complex, sister chromatid cohesion, spermiogenesis during postmeiotic stages, and checkpoints and factors required for the meiotic cell cycle .

The dynamic behaviou r of chromatid core formation suggests that this structure represents a real str cutural component existing in metaphase chromosomes and that it may play certain important role in the maintenance,stabilization and condensation of chromos omes.

染色体形成的动态行为，一方面暗示了这种结构在染色体集缩和维持中期染色体的形态方面起某种重要作用；另一方面说明了轴是染色体中存在的一种真实结构。

The markers usually used in the molecular epidemiologic study includes internal dose marker, Ames test, DNA adducts, and cytogenetic markers, e.g. chromosome abeeration, sister chromatid exchange and micronucleus.

本文讨论目前常用的生物侦测方法，包括内在剂量测定，致癌物—DNA结合物的生物有效剂量测定及生物效应的测定。

The results demonstrated that the dup(p21) and the del(p11) were of paternal origin and i was of maternal origin. The dup(p21) arose from an unequal sister chromatid exchange. The del(p11) occurred through X chromosom e breakage and deletion machanism.

结果表明，dup(p21)和del(p11)起源于父方，而i起源于母方。dup(p21)是由X染色体姊妹染色单体不均等的互换所引起的，del(p 11)是由于X染色体断裂后丢失所致，i的发生是由于卵母细胞X染色体着丝粒错分裂。
