Functional importance of poly(dA:dT) tracts in vivo. Poly(dA:dT) tracts — homopolymeric stretches of deoxyadenosine nucleotides (A's), often having lengths of 10–20 bp or even greater — are highly enriched in eukaryotic genomes but, intriguingly, not in prokaryotic genomes [], suggesting that they may have a functional role unique to eukaryotic genomes.

Also feasible with poly-dG and poly-dC. The nucleic acid activity of taxol and paclitaxel was investigated with synthetic and natural oligo- and polynucleotides.
