Methylation of DNA causes it to wrap tightly around histones, leading to decreased transcription. This is because the addition of a methyl group to the cytosine base of DNA can attract proteins that bind tightly to the histones, causing the DNA to become tightly wound and inaccessible to transcription factors.
