There are different areas that methylation occurs, including extensive areas of repetitive DNA sequences, such as centromeres and Transposons (Wang, 2004) (which are involved in chromosome stability), non-coding regions (Varambally, 2008) (Enhancer regions, miRNA) and within genes (Guenther, 2007).
Section Two: Biological Information and Genetic Theory Wells presents evidence for the functionality of non -protein-coding DNA to refute the concept of "junk DNA." This includes pervasive transcription of the genome, conservation of many nonprotein-coding sequences, sequence-dependent functions of RNAs transcribed from introns, pseudogenes, repetitive DNA, functions almost independent of the exact nucleotide sequence, chromatin topology in gene expression and centromere placement, and the light-focusing property of heterochromatin in inverted nuclei.
Telomeres are repetitive DNA sequences that sit at the ends of chromosomes and serve a protective function to make sure cells do not lose valuable genetic information each time they divide.
