Quizplus · Accepted Answer

The association of DNA with nucleosomes can create a compact and inaccessible structure, which can prevent transcription factors and RNA polymerase from accessing the gene to initiate transcription. This means that the default state for eukaryotic genes is to be turned off until regulatory mechanisms such as enhancers or silencers act upon them.
