Though the right border (RB) and left border (LB) of T-DNA are identical, the DNA transfer is specific for the DNA left of the RB (the T-DNA), rather than for the DNA left of the LB because

the sequence context at the LB defines the direction of transfer

the sequence context at the RB defines the direction of transfer

the sequence context at the LB defines the direction of transfer

the nuclear location sequence (NLS) of VirD2 protein drives the excised T-strand

the endonuclease activity of VirD2 protein allows nicking at RB

Though the right border (RB) and left border (LB) of T-DNA are identic
