Dynamic regulation of chromatin structure is of fundamental importance for modulating genomic activities in higher eukaryotes. The opposing activities of Polycomb group (PcG) and trithorax group (trxG) proteins are part of a chromatin-based cellular memory system ensuring the correct expression of specific transcriptional programs at defined developmental stages. The default silencing... https://www.ealisboa.com/amazing-find-Condor-ULH-Universal-Tactical-Leg-Holster-Right-Handed-Thigh-Rig-big-deal/
