Which epigenetic mark would you expect at the promoter region of an actively transcribed housekeeping gene?
Show answer and explanation
Correct answer: Unmethylated CpG island with histone acetylation
Active housekeeping genes typically have unmethylated promoter CpG islands and acetylated histones — creating open chromatin (euchromatin) accessible to transcription machinery.
