Fig. 1. Structures of RNA and morpholino oligonucleotides.

Fig. 1

(A) RNA oligonucleotide. (B) Morpholino oligonucleotide. Green ring represents the 6-membered morpholino ring (B), which replaces the ribose rings shown in (A). The non-ionic phosphorodiamidate linkages (B, red) replace the phosphodiester linkage in (A). Note the nBase (blue) can be any of the four standard bases (Adenine, Cytosine, Guanine or Thymine).
