有丝分裂前期 meaning in English
mitosis prophase
Examples
- Cyclin b can be a kind of mark protein which represents the process of prophase
细胞核中cyclinb的含量变化可以作为有丝分裂前期进程的标志。 - Cultured epithelial cell undergoing division . this cell is in prophase of mitosis . microtubules are shown in green , actin is in red and mitotic chromosomes are colored blue
以上两图为正处于有丝分裂前期的动物上皮细胞。绿色的是微丝,红色为肌动蛋白,染色质高度螺旋成为粗短的染色体(蓝色) ,核膜核仁逐渐解体,染色体不规则地分布于细胞内。 - Sds - page and western blotting of plasmodia of physarum polycephalum showed that cyclin b was present in the plasmodia of s phase , g2 phase , prophase , and metaphase . the molecular weight of cyclin b in physarum polycephalum was around 62kda . cyclin b was gradually accumulated from s phase to metaphase , and reached the maximal level at metaphase , however disappeared in the plasmodia of anaphase and telophase
Westernblotting分析结果表明, cyclinb存在于s期、 g _ 2期、前期和中期的原质团中,分子量约为62kda , cyclinb的含量从s期到中期逐渐增加,特别是有丝分裂前期增加明显,中期原质团cyclinb含量最高,后末期原质团中没有cyclinb 。 - After the nuclei of late g2 phase were incubated in the mitotic extracts harvested from metaphase plasmodia , the cyclin b in the nuclei gradually accumulated with the prolongation of incubating time . while , in the control group , the content of cyclin b changed little . this indicated that the mitotic extracts of metaphase plasmodia had the activity of accelerating the process of prophase , and the cell free system with mpf activity was established
将g _ 2晚期细胞核温育于中期提取物中,免疫印迹结果表明随着温育时间的延长,细胞核中cyclinb的含量逐渐增加,而在没有中期提取物的对照组细胞核中cyclinb含量并不随着温育时间的延长而增加,说明多头绒泡菌中期提取物具有促进有丝分裂前期进程的作用,同时也说明我们构建了具有mpf活性的非细胞体系。 - As cyclin b is the mark protein representing the process of prophase , we infered that cytochalasin b destroyed the polymerization of the nuclear actin and directly affected the process of prophase . nuclear actin played an important role in the process of the chromosome construction
因为cyclinb是有丝分裂前期进程的标志性蛋白,所以我们认为细胞松弛素b破坏细胞核内肌动蛋白聚合后,直接影响了有丝分裂前期的进程,进而悦明核内肌动蛋白在有丝分裂前期染色体构建过程中起着重要作用。
