| 1. | The plane of cell division is, in turn, determined by the orientation of the mitotic spindle .
细胞分裂的方向又是由有丝分裂的纺锤体所确定。 |
| 2. | The short answer is that no concise statement can yet be made which delimits the substances that stimulate cell division in quiescent cells .
简短的答案是还没有简明的结论来规定促进静止细胞中的细胞分裂的是哪些物质。 |
| 3. | The tips of chromosomes , called telomeres , shorten every time a cell divides
被称为调聚物的染色体尖端缩短了每次细胞分裂的时间。 |
| 4. | A synchronous mitotic experiment system that was in an unchanged culture condition was established
建立了多头绒泡菌自然同步化细胞分裂的实验体系。 |
| 5. | They gained control over a protein responsible for division , then halted and reversed the process
美国科学家们首先控制了负责细胞分裂的一种蛋白质，然后设法使该过程停止并最终将其逆转。 |
| 6. | The centromere is a specific genetic locus and remains relatively uncoiled during prophase , appearing as a primary constriction
着丝粒是一个特化的遗传区域，在细胞分裂的早期始终保持解开的结构，所以也叫做主缢痕。 |
| 7. | These pulses of electricity triggered a burst of biochemical activity , jump - starting the process of cell division , which was barely detectable
这些电脉冲激发了生物化学活度，触发细胞分裂的过程，而这种过程几乎是观察不到的。 |
| 8. | But out - of - control cell division can fuel cancer . they gained control over a protein responsible for division , then halted and reversed the process
美国科学家们首先控制了负责细胞分裂的一种蛋白质，然后设法使该过程停止并最终将其逆转。 |
| 9. | P70s6k can regulate stop mrnas through s6 protein . cdc2 can inhibit p70s6k to decrease the translation of stop mrnas , and then the biosynthesis is controlled
Cdc2在细胞分裂的过程中可以通过抑制p ~ ( 70 ) s6k来减弱具有5 top的mrnas的翻译，进而抑制合成代谢。 |
| 10. | Telomerase is at end of the telomere , it helps to keep the sequence of dna , to offset or postpone the continuously shortening of the telomere while the cell division takes place
端粒酶位于端粒末端，作用是合成端粒dna序列，以抵消或延缓端粒随细胞分裂的不断缩短。 |
