In this issue, Liu et al. (2009) report that maxicircle DNA copy number in trypanosomes is regulated by proteolysis of a helicase; the complex kinetoplast DNA system yields a clear view of how mitochondrial DNA replication can be regulated.
在本期杂志中，刘等人（2009年）报道，锥虫中的大环DNA拷贝数受一种解旋酶的蛋白水解作用调控；复杂的动质体DNA系统为线粒体DNA复制的调控方式提供了清晰的认识。
