Correct answer: C). They analyze the sequence of bases in the DNA to determine who committed a crime
The DNA profiling is used to identify the perpetrator. Forensics scientist is using the nucleotide sequence to find how who has done the crime. They study and analyze the DNA sequence in order to solve the crime.
DNA is used where a suspect is identified, the sample of suspected is compared to the evidence that is found at the crime scene. If the DNA sequence of the suspect is similar to the DNA, that is found at a crime scene. It means the crime is done by that person.
Hence, the correct answer would be option C.
