Monomers of a satellite DNA sequence of chaffinch (Fringilla coelebs L., Aves: Passeriformes) contains short clusters of the TTAGGG repeat
Rus. J Genetics — 2002. — V. 38, — P. 1359–1364.

A novel repeated sequence of chaffinch (Fringilla coelebs) designated as GS was isolated from genomic DNA after in vitro amplification of satellite DNA sequences using GSP-PCR technique. The proportion of this repeat in thechaffinch genome constitutes about 0.2%. Monomers are 176 to 199 bp in size and contain a short cluster of the TTAGGG telomeric tandem repeat. The oligomer of the telomeric hexanucleotid is flanked by the sequences that are significantly different in different monomers. The GS sequences are organized as tandemly repeated units and located in a number of chromomycin-positive blocks on the long arms of macrochromosomes 1, 2, 3, 5 and 6, as well as on several microchromosomes. This sequences homologous to the GS satellite of chaffinch were not found in the genomes of redwing (Turdus iliacus) and house sparrow ( Passer domesticus).
