BACKGROUND:Chromatin structure can control gene expression and can define specific transcription states. For example. bivalent methylation of histone H3K4 and H3K27 is linked to poised transcription in vertebrate embryonic stem cells (ESC). It allows them to rapidly engage specific developmental pathways. https://www.diegojavierfares.com/great-save-NAHMIAS-Miracle-Academy-T-shirt-Mens-Apparel-special-save/
