The ciliated protozoa undergo an extensive genome reorganization during the course of forming a transcriptionally active macronucleus. The process includes numerous chromosome fragmentation and DNA breakage and rejoining events. Recent work indicates that transposable elements play a role in the process.
纤毛原生动物在形成转录活跃的大核过程中经历广泛的基因组重组。该过程包括大量的染色体片段化以及DNA断裂和重新连接事件。最近的研究表明,转座元件在这一过程中发挥作用。
