Dt. Hickman et al., Kinetically selective binding of single stranded RNA over DNA by a pyrrolidine-amide oligonucleotide mimic (POM), NUCLEOS NUC, 20(4-7), 2001, pp. 1169-1172
Replacing the sugar-phosphodiester backbone of nucleic acids with a pyrroli
dine-amide backbone results in an oligonucleotide mimic POM 1 which binds w
ith high affinity and specificity to complementary DNA and RNA. Unlike othe
r modified oligonucleotides, PONT binds much more rapidly to single strande
d RNA than DNA.
