Secondary structure of influenza RNA motif.

<p><b>A.</b> M121, isolated RNA with consensus sequence; secondary structure was predicted by RNAstructure 5.5 using chemical mapping results from SHAPE. <b>B.</b> Chemical mapping results of M121 in entire segment 5 (+)RNA (A/VietNam/1203/2004 (H5N1)); in blue is marked difference in sequence comparing to M121 on panel A.</p>
