Characterization of chromatin distribution in cell nuclei

Webchromatin is highly compacted and thus very dark, we replace their values with grey value zero, that is BLACK. Where the chromatin has “cleared” we replace the value with 255, that is WHITE. Finally, where the chromatin remains approximately equal to the average value in the nucleus, the values are replaced with 128, GREY. WebThe packaging of chromatin into the nucleus of a eukaryotic cell requires an extraordinary degree of compaction and physical organization. In recent years, it has been shown that this organization is dynamically orchestrated to regulate responses to exogenous stimuli as well as to guide complex cell-type-specific developmental programs.
