List four steps an investigator should take to prevent contamination of DNA evidence.

What will be an ideal response?


To minimize the possible occurrence of contamination of biological evidence, the investigator should change gloves before handling each new piece of evidence, collect a substrate control for possible subsequent laboratory examination, pick up small items of evidence such as cigarette butts and stamps with clean forceps, and always package each item of evidence in its own well-ventilated container. Safety considerations and avoidance of contamination also call for the wearing of face masks, a lab coat, eye protection, shoe covers, and possibly overalls.
