Final answer:
DNA identification involves comparing DNA sequences to determine relationships between individuals. Fingerprints can identify people, but they do not provide genetic information like DNA does.
Step-by-step explanation:
DNA identification works by comparing the DNA sequences of different individuals to determine if they are related. This is done by extracting DNA from a sample, amplifying it using PCR, and then analyzing it using various techniques. One common technique is DNA fingerprinting, which involves cutting the DNA into pieces, separating them on a gel through electrophoresis, and studying the resulting patterns. By comparing the patterns of different individuals, it is possible to determine their relationship.
Fingerprints, on the other hand, are unique to each individual and can be used to identify people. However, fingerprints cannot be used in the same way as DNA identification because they do not provide genetic information. While DNA can determine if two individuals are related, fingerprints can only identify an individual based on the unique patterns on their fingers.
