Downtown Life Science Students Extract DNA

January 26, 2023

In the seventh-grade Life Science classes, students have been exploring the amazing intricacies of deoxyribonucleic acid (DNA).

IMG_5767IMG_5671DNA is the genetic material that carries all of the information about an organism and directs all the functions of each cell. Students learned about the double helix structure of DNA, including the nitrogen bases adenine, thymine, guanine, and cytosine, as well as the backbone molecules deoxyribose and phosphate.

In the lab this week, students extracted actual DNA from organisms! With parent/guardian permission, they will even extract their own DNA!
