Unexpressed genes are often found in regions of the DNA molecule where the chromatin is condensed and tightly packed. Such regions are inaccessible to RNA polymerase enzyme and other transcription factors, which are required for gene expression. Unexpressed genes may also be found in regions of repetitive or non-coding DNA, or in regions that are spliced out or degraded during post-transcriptional processing.
