Gene Regulation: Operons and Epigenetics · Zoology

Heterochromatin is generally associated with:

  1. Elevated gene expression levels
  2. Transcriptional inactivity
  3. Active regulatory enhancers
  4. Rapid mRNA processing
Show answer and explanation

Correct answer: Transcriptional inactivity

Heterochromatin is densely packed, making DNA inaccessible to transcription machinery. It is generally transcriptionally inactive and often contains repetitive sequences such as centromeric and telomeric DNA.
