Dideoxynucleotide sequencing (lanes 1-4) was performed with BLoli1116 and a cloned fragment of the ter1+ gene. Normal telomere length was restored by combining complementary nucleotide substitutions in both elements, showing that base pairing, not a specific sequence, limits reverse transcription beyond the template. Chem. 278 (35): 32493–6. DOI:10.1074/jbc.C300226200.

These stacking effects are unique to double-stranded sequences, which to a large extent keep their structure.
