Chromatin
Chromatin is a complex of protein and DNA. The staining characteristic of chromatin indicates the level of transcriptional activity in the cell. These light micrographs contrast euchromatin, which is pale-staining and transcriptionally active, with heteochromatin, which is dark staining and transcriptionally less active.
