Final answer:
Each different band on a DNA fingerprint represents a unique DNA pattern, which is determined through gel electrophoresis. The bands correspond to different fragments of DNA, and each individual will have a unique pattern of bands.
Step-by-step explanation:
In DNA fingerprinting, each different band represents a unique DNA pattern. These bands are produced through a process called gel electrophoresis, where DNA samples are cut with restriction enzymes and separated based on their size and charge. The larger DNA fragments move slower and are located near the top, while the smaller fragments move faster and are near the bottom. The bands on the gel represent different fragments of DNA, and each individual will have a unique pattern of bands.
