The actual residues in a DNA-binding protein that interacts with DNA usually correspond to each other according to the amino acids encoded by the DNA.For example,a DNA sequencing containing AGC-AGA-CAG which encodes for Ser-Arg-Gln would likely have a DNA-binding protein with Ser-Arg-Gln bind to it.

The sequence of amino acids in a DNA-binding protein does not directly correspond to the DNA sequence it binds to. DNA-binding proteins recognize specific DNA sequences through structural motifs and interactions, not by having a matching amino acid sequence.
