| As you have probably heard everyone carries their own DNA, one that no one else in the world carries. This is because of the unique sequencing in the DNA strands. Although when it comes to identifying people its not about identifying the unique sequence, it's about the analysis of the "mitochondrial" DNA. This means to observe the D-Loop (displacement loop) and STR's (short tandem repeats). By observing the D-Loop it makes it possible because the polymorphisms of the sequence(s) will result in the substitute of base pairs during DNA replication. This means that by using polymorphis, it will help breakdown DNA to the point where only the substitute of base pairs are present, therefore giving us there specific genetic information. |
