Schematic representation of the assembled data from Drosophila telomeres (source: http://flybase.org webcite). XL, left telomere chromosome X (aprox. 20 Kb). 4R, right telomere chromosome 4 (aprox. 70 Kb). Names of HeT-A copies are indicated. Domains of complete HeT-A element, 5'UTR, gag gene and 3'UTR (dotted, smooth and lined boxes, respectively) are indicated.
