One Would Expect Heterochromatic Regions of DNA to Be More

Question

One would expect heterochromatic regions of DNA to be more compacted than euchromatic regions.

Accepted Answer

Heterochromatic regions of DNA are typically more compacted than euchromatic regions. This is because heterochromatin contains highly repetitive DNA sequences that are tightly packaged and often transcriptionally silent. In contrast, euchromatin contains more loosely packaged DNA that is accessible for transcription and other DNA-based processes.
