1.
Effect of inhibiting the first polar body (PB1) on chromosome segregation in fertilized eggs and ploidy composition of 4～8 cell embryos was studied in Zhikong scallop, Chlamys ferreri.
结果发现,抑制第一极体显著改变了受精卵的染色体行为,在第二次减数分裂过程中共发现4种典型染色体分离类型,分别是三极分离(41。
2.
The faithful chromosome segregation is crucial for transmitting the genetic information accu- rately in eukaryotic organisms.
染色体分离是真核生物正确传递遗传信息的关键。
3.
Streptomyces coelicolor A3(2) does not have a canonical cell division cycle duringmost of its complex life cycle, yet it contains a gene (ftsK_(SC)) encoding a protein similar toFtsK, which couples the completion of cell division and chromosome segregation inunicellular bacteria such as Escherichia coli.
大肠杆菌的ftsK是同时参与新生横隔的形成以及染色体分离的细胞分裂必需基因。
