'profase'是英语单词,翻译为中文是“前期”。在生物学领域中,'profase'是指有丝分裂期的第一阶段,包括细胞核逐渐缩小、染色体逐渐凝聚、核仁消失等过程。
以下是9个含有'profase'的例句:
1. During profase, the chromatin condenses and becomes visible as chromosomes.(在前期期间,染色质凝聚并变成了可见的染色体。)
2. The spindle fibers begin to form during profase.(纺锤体纤维在前期开始形成。)
3. In animal cells, the centrioles move towards the poles of the cell during profase.(在动物细胞中,中心粒在前期向细胞极移动。)
4. One of the key events in profase is the pairing of homologous chromosomes.(前期的关键事件之一是同源染色体的配对。)
5. Nuclear envelope breakdown occurs at the end of profase.(核膜在前期末期发生崩解。)
6. The duration of profase varies depending on the organism and the cell type.(前期持续时间因生物体和细胞类型而异。)
7. Mutations in genes involved in profase can lead to chromosomal abnormalities.(参与前期的基因发生突变可以导致染色体异常。)
8. The length of profase is often used as an indicator of the overall length of the cell cycle.(前期的长度通常被用作细胞周期总长度的指标。)
9. Researchers are still exploring the molecular mechanisms that control the progression of cells through profase.(研究人员仍在探索控制细胞通过前期的分子机制。)
