Experimentally verified and predicted telomere sequence motifs from more than 9000 species are collected in research community curated database [http://cfb.ceitec.muni.cz/telobase/ TeloBase]. Some of the experimentally verified telomere nucleotide sequences are also listed in [http://telomerase.asu.edu/sequences_telomere.html Telomerase Database] website (see nucleic acid notation for letter representations).
