DNA trace analysis

DNA trace analysis involves examining tiny amounts of genetic material left at crime scenes or evidence to identify individuals. These small DNA samples can come from skin cells, hair, or bodily fluids. Scientists extract and analyze this DNA to create a genetic profile, which can then be compared to suspects or databases. This process is highly sensitive, allowing for accurate identification even from minimal evidence, making it a crucial tool in forensic investigations to establish connections or exclude individuals with a high degree of certainty.
