19-mer variants. (A) Sequence of the RNA variants of the D-loop of the 19-mer and the CE-loop of 35 -uucg. Substituted residues are shown in red. (B-D) Imino region of 1H-15N HSQC spectra of (B) the labeled 19-mer/non-labeled 35 -uucg heterodimer, of (C) the labeled 19C/non-labeled 35 -uucg mixture and of (D) the labeled 19E/non-labeled 35 -uucg mixture.
