specific binding

in DNA-protein interactions
https://doi.org/10.1351/goldbook.09881

Binding of proteins to specific sites in deoxyribonucleic acid (DNA) based on the precise recognition of nucleotide sequence and/or conformation of the DNA.

Note: Sequence-specific DNA binding is typical for restriction enzymes, transcription factors and other proteins involved in cellular regulation, etc.
