Why is DNA fingerprinting so useful in criminal investigations?

Question

Quizplus · Accepted Answer

DNA fingerprinting is useful in criminal investigations because no two people, other than identical twins, have the same DNA. This means that DNA evidence found at a crime scene can be traced back to a specific individual, helping to identify suspects and solve crimes.

Answer: B is incorrect, as not all crime scenes may have useable DNA evidence.

Answer: C is incorrect, as obtaining DNA from a suspect usually requires a warrant or their consent.

Answer: D is incorrect, as DNA evidence can be subject to interpretation and analysis, and may not always be conclusive on its own.
