degree to which DNA is exposed for cellular processes

Chromatin accessibility refers to how easily DNA can be reached and read by cellular machinery. In simple terms, it's like how open a book is: if the pages are tightly closed, it's hard to read, but if they're open, it's easy. For professionals, it indicates the degree to which chromatin structure allows transcription factors and other proteins to interact with DNA, influencing gene expression and cellular function.
