# Sequence dependent interactions between Nucleic Acids

The sequence dependent pairing of ssDNA with ssDNA is well known; however, the Prentiss group has shown that dsDNA-dsDNA pairing can also be sequence dependent. https://www.pnas.org/content/106/47/19824.short

In addition, the stringency of the pairing between long ssDNA molecules can be enhanced by inserted abasic sites into one of the ssDNA strands.

Finally, sequence dependent interactions between ssDNA and dsDNA can bring dsDNA molecules together
