  • During differentiation, many developmental promoters remain poised with paused polymerase ready for rapid activation.

Examples

  • Chromatin modifications left the enhancer poised, enabling a quick transcriptional response when signals arrived.

  • The gene is poised for activation in response to stress.

  • Researchers found genes poised in stem cells that later switched on during early embryonic stages.

  • RNA polymerase is poised at the promoter region.

  • During differentiation, many developmental promoters remain poised with paused polymerase ready for rapid activation.

  • Chromatin modifications left the enhancer poised, enabling a quick transcriptional response when signals arrived.

  • Researchers found genes poised in stem cells that later switched on during early embryonic stages.

Morphology

poised = poise (semi-transparent) = poise + d

Morphologically formed from 'poise' + '-d', but the sense is a domain-specific metaphor ('prepared for rapid activation') that requires biological knowledge.

Etymology

In biology the word poised keeps the same picture of balance: it began from a word for weight and the Latin pendere 'to hang', so it means being held in careful balance. That's why genes or molecules called poised are kept in a ready state and can be turned on quickly.
