Schematic of the junctional modifications during VDJ rearrangement, showing the locations and the occurrence of different types of junctional modifications. 3VP and 3VT: the palindromic nucleotides (P) additions and exonuclease trimmings observed at 3′-end of V regions, respectively; 5DP and 5DT: the P additions and exonuclease trimmings observed at 5′-end of D genes, respectively; 3DP and 3DT: the P additions and exonuclease trimmings observed at 3′-end of D genes, respectively; 5JP and 5JT: the P additions and exonuclease trimmings observed at 5′-end of J genes, respectively; N1: the non-template randomized nucleotides (N) additions happened at the region between the 3′-end of V gene and the 5′-end of D gene; N2: N additions happened at the region between the 3′-end of D gene and the 5′-end of J gene.
