Euchromatin is loosely coiled DNA that is transcriptionally active. An increased amount of euchromatin indicates an active cell. Heterochromatin is tightly packed DNA that is transcriptionally innactive.
Heterochromatin is more densely packaged than euchromatin and is much less transcriptionally active. Examples of heterochromatic DNA would be the centromeric and telomeric regions of a chromosome.
