Elwood Middle School seventh-graders recently learned about how to analyze and identify DNA with the help of the Cold Spring Harbor DNA Learning Center. Over the course of two days, the classes conducted an experiment with an educator from the DNA Center.

The in-class forensic lab allowed students to look at chromosomes and sequencing DNA to gain a better understanding of how DNA works. They also learned about the scientists that made strides in the research world of genetics.

The classes were introduced to SYBR Green, a special gel that dyes the DNA, allowing it to be seen and glow under an ultraviolet light. Students took turns analyzing the DNA under the light with their peers and recording their results.
