Extended Data Fig. 7: tRNAGln isoforms with their associated cryo EM density.
From: tRNA as an assembly chaperone for a macromolecular transcription-processing complex

Comparison of the tRNAGln-UUG model with its associated cryo EM density as extracted from the complete vRNAP structure (left) to a model for the tRNAArg-CCG sequence, modelled manually into the complete vRNAP density (right). Both sequences fit the density well, except for the “extra” base G48 in the tRNAArg-CCG sequence.
