DNA not wrapped around histones is not transcribed but is susceptible to degradation by DNase.

  

DNA that is not condensed into chromatin is transcribed and also protected from DNase degradation.

  

DNA wrapped around histones is not transcribed and is protected from degradation by nucleases.

  

Only single-stranded DNA is transcriptionally active and can be broken down by nucleases.
