How is dna fingerprinting done in a crime lab
help i’ll give brainlest

There are various methods for analyzing DNA to establish if two samples are the same or different. This is sometimes referred to as DNA fingerprinting. For example, two cloned pieces of DNA can be studied in the laboratory to determine if they have portions in common, and thus overlap with one another. In a different setting, such as a crime scene, DNA samples can be collected and analyzed to determine if they match DNA samples obtained from suspects of that crime. If two DNA samples have the same fingerprint, then there is a very high statistical likelihood that they came from the same person. Such an approach can also be used to establish paternity.
