Extended Data Figure 4: Backbone model of MS2 genome segment 881–1290.
From: In situ structures of the genome and genome-delivery apparatus in a single-stranded RNA virus
Part of the traced backbone model of MS2 genome (top panel; rainbow-coloured blue to red from 5′ to 3′) is compared with the predicted secondary structure (bottom panel) of genome sequence 881–1290. Matching stem–loops in the two are marked with the same letter. Atomic models of high-resolution stem–loops (ribbons in top panel) contained in the segment are also shown. Some of the base pairings in the predicted secondary structure have been modified to make it more consistent with the observed structure.
