🧬 As we wrap up #ForensicScienceWeek, we’re stepping into the DNA lab to learn about DNA extraction. First, our #scientist uses an instrument to heat & shake samples with reagents. This pulls DNA off of swabs/evidence & transfers it into a liquid. This step also breaks open cells, making DNA accessible. ⛓️‍💥 After carefully comparing case/item numbers, she loads liquid samples onto a rack & into the instrument, which “cleans up” samples. It also uses tiny magnets to collect & separate out DNA.

NATIONAL FORENSIC SCIENCE WEEK 🔬 Scientists in the Biology/DNA section of the laboratory screen items of evidence that are submitted to the Crime Laboratory Division from crime scenes to locate possible sources of DNA on these items. DNA profiles can be developed from a variety of sources including blood stains, semen, tissue, saliva, and hair roots. During DNA analysis, a DNA profile is developed from crime scene samples and known reference samples collected directly from persons of interest.
