the readily stainable substance of a cell nucleus consisting of DNA and RNA and various proteins; during mitotic division it condenses into chromosomes
The key to nuclear transplantation with adult cells lies in nuclear reprogramming or chromatin remodeling. 成年细胞核移植的关键在于核的再编序或核染质的再塑造。
Human embryos do not provide enough time for chromatin remodeling, thus preventing the cloning of humans using adult cells. 人类胚胎没有足够长的时间进行核染质的再塑造，因而妨碍了用成人细胞克隆人类。
Methylation of chromatin causes it to condense. 染色质甲基化后会出现凝缩。
The chromatin was polymerized and concentrated and the nucleolus was dispersed. 细胞核变形，核膜破裂，核质外流，染色质凝集，核仁解体。
