Kinetically selective binding of single stranded RNA over DNA by a pyrrolidine-amide oligonucleotide mimic (POM)

Replacing the sugar-phosphodiester backbone of nucleic acids with a pyrrolidine-amide backbone results in an oligonucleotide mimic POM 1 which binds with high affinity and specificity to complementary DNA and RNA. Unlike other modified oligonucleotides, POM binds much more rapidly to single stranded RNA than DNA.
