Ensuring Accuracy and Legal Standards. This technique, also known as DNA profiling, analyzes specific regions of a person’s genome to create a pattern that is virtually unique to that person.
Forensic DNA Fingerprinting in Criminal Investigations
The chance of two unrelated individuals having the exact same STR pattern at all tested locations is astronomically low, often quoted as one in billions or higher. A child inherits half of their DNA from their biological mother and half from their biological father.
It is used in organ transplantation to find compatible donors by comparing genetic markers. This amplification is necessary because the genetic material found at crime scenes or from old samples might be minimal or degraded.

This technology has revolutionized how we solve crimes, establish paternity, and understand human history. Scientists extract the DNA from these cells and focus on specific regions of the genome known as Short Tandem Repeats, or STRs.
