Introns

Non-coding sections of DNA within a gene that are removed via RNA splicing during the process of transcription.

Exons

Segments of DNA or RNA that encode portions of the final mature RNA product after splicing has removed introns.

DNA Methylation

A process in which gene inactivation is perpetuated by enzymes that add methyl groups to DNA.

Heterochromatin

Highly coiled and compacted chromatin in an inactive state. Compare with euchromatin.
