Abstract
Different heterochromatic properties appear on satellite DNA during successive embryonic division cycles in Drosophila. One such property, late replication, precedes HP1 recruitment, is under the control of zygotic transcription, and helps to lengthen S phase.
摘要
在果蝇的连续胚胎分裂周期中，卫星 DNA 上会出现不同的异染色质特性。其中一个特性是晚期复制，它先于 HP1 募集发生，受合子转录的控制，并有助于延长 S 期。
