From: Telomeric retrotransposons show propensity to form G-quadruplexes in various eukaryotic species
Visualization of LINE retrotransposons arrays with PQS in telomeric sequences of various Drosophila species. Mutual strand-specific orientation of LINEs and PQS is depicted. The order and taxonomic division of given species was adapted from the Drosophila genus consensus phylogenetic tree in [24]. The gray colored boxes in D. virilis are formed by tandem repeats TTR321 and TTR712. The PQS rich region in D. willistoni is formed by 392 bp long tandem repeat. Note that in each species there is at least one element with antisense PQS
