  • PubMed Abstract: 

    Telomeres, the structures at the ends of linear eukaryotic chromosomes, are essential for chromosome replication and stability. The telomeres of the unicellular ciliate Oxytricha contain a 3' single strand overhang composed of two repeats of the telomere repeat sequence d(TTTTGGGG). It has been proposed that oligonucleotides containing this repeat can form DNA quadruplexes via hydrogen bonding of the guanines into quartets. Such structures may be relevant to the biological function of the telomere, and in G-rich sequences elsewhere in the genome.
