Interstitial telomeric sequences in vertebrate chromosomes: Origin, function, instability and evolution
AD Bolzán - Mutation research/Reviews in mutation research, 2017 - Elsevier
By definition, telomeric sequences are located at the very ends or terminal regions of
chromosomes. However, several vertebrate species show blocks of (TTAGGG) n repeats …
