G-quadruplexes within prion mRNA: the missing link in prion disease?

abstract：:A study of the activity of deoxyribonucleotide-substituted analogs of the hammerhead domain of RNA catalysis has led to the design of a 14mer oligomer composed entirely of deoxyribonucleotides that promotes the cleavage of an RNA substrate. Characterization of this reaction with sequence variants and mixed DNA/RNA oli...
