This review explores recent emerging insights into enhancer action, focusing on underexplored aspects such as the physical size of regulatory elements, the stochasticity of transcription factor binding and chromatin structure, and the role of nonlinear processes in reconciling longstanding discrepancies between theoretical models and experimental observations. Together, these insights provide a nuanced view of enhancer biology, highlighting the complexity of gene regulation and the need for innovative methodologies to further decode enhancer mechanisms.
