===Telomeres===
{{Main|Telomere}}

Telomeres are regions of repetitive DNA at the end of a [[chromosome]], which provide protection from chromosomal deterioration during [[DNA replication]]. Recent studies have shown that telomeres function to aid in its own stability. [[Telomeric Repeat-Containing RNA (TERRA)|Telomeric repeat-containing RNA (TERRA)]] are transcripts derived from telomeres. TERRA has been shown to maintain telomerase activity and lengthen the ends of chromosomes.<ref>{{cite journal | vauthors = Cusanelli E, Chartrand P | title = Telomeric noncoding RNA: telomeric repeat-containing RNA in telomere biology | journal = Wiley Interdisciplinary Reviews.
