Fig. 3: The secondary structure of the SARS-CoV-2 genome.
From: The architecture of the SARS-CoV-2 RNA genome inside virion
The known structural elements in the 5′ UTR, the frame-shifting element (FSE), and the 3′ UTR are labeled or marked in blue. The pairwise interaction strength was quantified and shown in different colors. Black arrows highlight highly confident long-range duplexes measured by vRIC-seq signals. Green and cyan boxes mark the start and stop codons, respectively. Purple boxes and arrows outline the core sequence (CS) of each transcription-regulatory sequence (TRS).
