WebChromatin is a complex of DNA and protein found in eukaryotic cells. [1] The primary function is to package long DNA molecules into more compact, denser structures.

WebApr 7, 2024 · The investigators proposed that the condensed euchromatin model outlined in this study includes a mechanism in which chromatin's stickiness is reduced when acetyl groups are added to histones. The structure of chromatin can thus be opened so large molecules like transcription or replication factors can move in and regulate gene expression.
