The task‚ which was successfully carried out was to determine whether DNA from suspects A‚ B or C matches the sample of blood found at the murder scene (X). The process of PCR acts in the same way as DNA replication but is restricted to specific DNA samples of interest. By amplifying the necessary DNA sequence‚
