Statistical results of base mutations in non-redundant DGRs (a, b) and an example of DGR with Non-A-to-N substitutions (c). (a) Proportions of mutated bases in TRs; (b) Directions of base mutations. The four mutated bases are shown in different columns, and the mutation direction is shown by a ratio; (c) This DGR from NZ_JIDJ01000049.1 contains one TR template and two VR elements, which located in C-terminal of target genes. In VR1, three thymine were substituted by other bases
