“…This is a major gap in our understanding because RNA structural elements in positive strand viruses play central roles in regulating all aspects of replication, translation, packaging and host defense ( McMullan et al, 2007 , Fricke et al, 2015 , Pirakitikulr et al, 2016 , Clyde and Harris, 2006 , MacFadden et al, 2018 ), so an understanding of their location and function is critical for mechanistic understanding and strategies for viral control( Barrows et al, 2018 , Adams et al, 2017 ). Given the success of antimicrobials targeted against conserved RNA structural elements in other pathogen genomes( Warner et al, 2018 , Fedorova et al, 2018 ), there is an urgent, unmet need to elucidate the genome architecture of SARS-CoV-2.…”
