Abstract
A mitotic checkpoint arrests cell cycle progression in response to spindle damage. It now appears that this checkpoint has two separate arms, one that prevents anaphase and a second that prevents cytokinesis and DNA re-replication.
摘要
有丝分裂检查点会响应纺锤体损伤而阻止细胞周期进程。现在看来，这个检查点有两条独立的途径，一条阻止后期，另一条阻止胞质分裂和DNA再复制。
