Rye Neck Middle School Students Study Their DNA

As part of their eighth-grade biology studies, Rye Neck Middle School students in Linette Milo's Living Environment classes recently isolated their own human genomic DNA and created a wearable DNA necklace.

“Each student extracted crude DNA from his or her own cheek cells,” Milo said. “During the procedure, they lysed a sample of their cheek cells and watched as wispy white strands of their own chromosomal DNA precipitated out of solution in the presence of ethanol.”

At the end of the activity, the students transferred their DNA to a plastic microcentrifuge tube before fashioning it and string into a DNA pendant necklace.
