Morphology

bar + code

The term builds directly from 'bar' (a stripe) + 'code' (an identifying label): a barcode is an identifying code represented by bars, so a learner who knows both words can infer it denotes an identifying marker. The DNA usage is a metaphorical extension of the same identifying-code concept but remains compositionally transparent and cross-linguistically recognizable.

Etymology

The noun bar code comes from the printed picture of black vertical bars that form a machine 'code'. Scanners read those lines to 'identify' items and give their price, so the name now means the patterned label on products.
