Abstract
In isolated interphase mouse liver nuclei after hypotonic treatment only the chromocenters belonging to the pericentromeric heterochromatin remain in dense form while the main mass of a chromatin is completely decondensed. The centromeric nature of these chromocenters is demonstrated by their capability for C-banding and for hybridization with a satellite mouse DNA.
摘要
在低渗处理后的离体间期小鼠肝细胞核中，只有属于着丝粒周围异染色质的染色中心保持致密形态，而染色质的主要部分则完全解聚。这些染色中心的着丝粒性质通过它们进行C带染色以及与小鼠卫星DNA杂交的能力得以证明。
