What does chromatin consist of?

Chromatin is a complex of DNA and proteins that forms chromosomes within the nucleus of eukaryotic cells. It primarily consists of DNA wrapped around histone proteins, which help organize and condense the DNA into a compact structure, making it possible for it to fit into the cell nucleus. In addition to histones, chromatin can also contain other proteins that play roles in gene regulation and DNA packaging. While RNA can be associated with chromatin during certain processes, such as transcription, the defining structure of chromatin itself comprises DNA and proteins. Therefore, the correct choice captures the essential components of chromatin: DNA and proteins, acknowledging the important role that proteins have in the structure and function of chromatin.
