Pick one technique used in the paper that measures an epigenetic feature (for example, ChIP-qPCR, ChIP-seq, ATAC-seq, bisulfite sequencing, CUT&RUN, etc.).

A. Name the technique and, in simple terms, explain what it measures.

B. Based on a result in the paper using this technique, give:

• One thing the authors can safely conclude about gene regulation or chromatin state.
• One thing they cannot conclude from this technique alone (for example, they might see correlation but not prove cause-and-effect).
