Faithful chromosome segregation is accomplished by attachment of chromosomes to spindle microtubules using the kinetochore. In a major step forward in understanding the functional and structural complexity of kinetochores, a 21-subunit human centromere - kinetochore complex has been reconstituted entirely from purified components, recreating the connection between DNA and microtubule.
染色体的正确分离是通过动粒附着于纺锤体微管来实现的。在深入理解动粒的功能和结构复杂性方面迈出了重要一步,一个由 21 个亚基组成的人类着丝粒-动粒复合物已经从纯组分中完全重建,重新建立了 DNA 和微管之间的连接。
