Cap-H2 antagonizes the formation of these structures. They facilitate zeste (ZEST)-white interactions by promoting transvection, and widely-used guides to their structure were generated by Bridges and Lefevre.

In these structures, Balbiani rings form in response to increased concentrations of ecdysone. Indels appear as looped-out regions in these structures, and P elements localize to their chromocenters. Frequently found in secretory tissues, these structures are often extracted from the salivary glands of heat-shocked larvae to visualize "puffs" along their length at sites of active transcription. For 10 points, name these structures seen in insects like Drosophila in which one to two thousand identical chromosomes are bundled together laterally.
