The chromatin packaging of the genome is dynamic, changing with the cell cycle and with transcriptional regulation. During mitosis, chromatin is condensed for segregation of chromosomes, while for transcription chromatin is more open. The nuclear matrix, or scaffold, is a protein network in the nucleus providing structure and regulating chromatin condensation. Regulated interactions of matrix proteins with each other......閱讀全文
