From: Retroviral PBS-segment sequence and structure: Orchestrating early and late replication events
Secondary structure of the PBS-segment modeled by NMR and chemical probing taking into account potential transcription start site heterogeneity. A. The secondary structure model of the dimeric 5’UTR was determined by NMR [74, 93]. B-C. The secondary structure model of 5’UTR starting with GG and GGG, respectively (B and C) based on FARS-seq (79). D-E. The secondary structure model of 5’UTR starting with GG and GGGG, respectively (D and E) based on in-gel SHAPE [79]. Purple, tRNA annealing sequence; Red, dimer-promoting sequences, DIS
