DNA Crime

DNA Crime

DNA evidence has started to play a big part in many nations' criminal justice systems. It has been used to prove that suspects were involved in crimes and to free people who were wrongly convicted. In the United States, it has been integral to several high-profile criminal cases.

The exact steps in preparing and analyzing the DNA can vary based on which method the investigators use. But, in general, the tests examine non-coding portions of DNA strands. Genes, who serve as templates for making proteins in your cells, make up only five percent of a DNA strand. The remainder of your DNA is non-coding and includes lots of repeating base pairs. Different types of tests look for and analyze different base pair repetition patterns.
Polymerase Chain Reaction (PCR)
Polymerase Chain Reaction (PCR)
Polymerase Chain Reaction (PCR) analysis is a newer technique that can amplify the DNA in a much smaller sample. It does this by making lots of identical copies of a small amount of DNA. It's often used as a preliminary step in Short Tandem Repeat (STR) analysis, which is the most commonly-used type of forensic analysis today.
Restriction Fragment Length Polymorphism (RFLP)
Restriction Fragment Length Polymorphism (RFLP) analysis was one of the first forensic methods used to analyze DNA. It analyzes the length of strands of DNA that include repeating base pairs. These repetitions are known as variable number tandem repeats (VNTRs) because they can repeat themselves anywhere from one to thirty times.
