About the DNA Learning Center
DNA Learning Center logo Since the DNA Learning Center was established in 1988, we've been advancing genetics education for students and families. We deliver biotechnology instruction through laboratory field trips, summer camps, and independent research programs for students in New York and beyond. More than 750,000 middle and high school students have experienced our hands-on approach to science instruction over the last 35+ years. We also offer up-to-date teacher training through biology workshops and professional development for teachers in genetics and biotechnology.
