These are gene-rich, tend to have high GC content, and contain epigenetics marks for active transcription

Final answer:

Gene-rich regions with high GC content and epigenetic marks for active transcription have accessible DNA and promote gene expression. DNA methylation and histone modifications play a role in altering nucleosome spacing and regulating gene activity.

Step-by-step explanation:

These gene-rich regions have high GC content and contain epigenetic marks for active transcription.

DNA methylation and chemical modification of histone tails alter the spacing of nucleosomes, making the DNA accessible and promoting gene expression.

Highly methylated DNA regions with deacetylated histones are transcriptionally inactive.
