4) chromosome microdissection
染色体显微切割
1.
Probes for X and Y chromosome were obtained from the number 1 chromosomes of XX and YY genotypes of Nile tilapia, Oreochromis niloticus ,by chromosome microdissection.
通过染色体显微切割的方法 ,分别从尼罗罗非鱼XX和YY个体有丝分裂中期相染色体滴片上 ,割取第 1对染色体 ,随后经简并PCR扩增 ,分别用生物素和地高辛标记 ,得到X和Y染色体探针。
5) Chromosome Segregation
染色体分离
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。
