Question

using the codis database in dna profiling is one of the best sources of physical evidence to identify the guilty party because
a persons dna profile is unique to only that person and found in every cell of the body, some of which are often found at the scene of the crime
the fbi and the courts have agreed to accept this evidence above all else in a conviction
every type of crime is going to have dna evidence of some sort
the analysis of the dna is a very easy process and mistakes seldom occur

Explanation:

DNA profiling is effective because each person's DNA profile is unique and present in body cells that can be found at crime scenes. The FBI and courts accepting it is a result of its uniqueness, not the main reason for its effectiveness. Not all crimes have DNA evidence, and DNA analysis is complex with potential for errors.
