Which statement correctly describes non-coding RNAs (ncRNAs) in epigenetic regulation?
Show answer and explanation
Correct answer: ncRNAs recruit chromatin-modifying complexes to specific loci
Non-coding RNAs (like lncRNAs or miRNAs) can guide chromatin-modifying complexes to particular genomic regions, influencing chromatin state and gene expression without altering DNA sequence.
