Concept explainers
a.
To explain: The way in which the data that were obtained from the crime that had occurred.
Introduction: Short tandem repeats (STRs) are the repeated sequence of one to five
b.
To determine: The suspect who is to be charged of the crime from the obtained data.
Introduction: Polymerase Chain Reaction (PCR) is a technique used to amplify very poor amounts of DNA present in the cell. In this technique, specific primers and polymerase enzymes are added followed by alternate heating and cooling to denature and anneal the DNA fragments. Thus, it plays a vital role in DNA analysis because it produces millions of copies of DNA in a short period of time in a parallel way.
