Educator Training
We offer up-to-date teacher training through biology workshops and professional development for teachers in genetics and biotechnology. With federal and private foundation funding, we offer these free workshops to middle school, high school, and college educators, especially those in the areas of genetics, biology, genomics, and bioinformatics.
The Cold Spring Harbor Laboratory DNA Learning Center is an approved Sponsor of Continuing Teacher and Leader Education (CTLE).

Join us this spring to see how nanopore sequencing—a portable, cost-effective alternative to traditional commercial services—can be integrated into your classroom. This workshop demonstrates how to use nanopore technology for real-world applications, including generating DNA barcodes and performing microbiome or metabarcoding analyses.
The DNA Learning Center and Oxford Nanopore have collaborated to adapt these professional workflows for education, streamlining the protocol to ensure the technology is accessible for student use. Additionally, we will showcase the redeveloped DNA Subway 2.0, which now supports full mobile use and a dedicated line for metabarcoding analysis, enabling users to “analyze anywhere”.
Finally, attendees will learn how the DNALC’s Nanopore Research Accelerator partnership can offer ongoing support for implementing these projects in their own schools.

The Genetics of Lactase Persistence
Try our newest lab - coming in fall 2026*
Most mammals, including many humans, become lactose intolerant after weaning due to decreased expression of the lactase gene. Some people have genetic mutations that allow them to continue producing lactase into adulthood, a trait called lactase persistence. Lactase persistence has become more common over time through natural selection, especially in populations where dairy farming and dairy consumption were important parts of the culture.
In this session participants will use agarose gel electrophoresis to detect mutations in the lactase enhancer region. The results will reveal if individuals have a lactase persistence mutation. Participants will also compare parent and child genotypes to understand how the lactase persistence mutations are inherited.
Training will focus on lab skills and conceptual connections. This workshop is appropriate for Life Science, Genetics, Biology, and AP Biology teachers. The experiment aligns with concepts covered in the new Regents Life Science investigation on lactose intolerance, but the laboratory techniques and concepts are also applicable to other areas of biology learning.
There is no charge to attend this teacher workshop. Participants may receive CTLE hours, if requested.
*This two-hour lab will be available as a field trip beginning in fall 2026. A more advanced four-hour version will also be available for students to analyze their own DNA for a lactase persistence mutation!

Bacterial Transformation and Restriction Analysis
Join us to review two classic biology experiments!
Thursday, June 4, 2026
9:30 a.m.–3:00 p.m.
DNA Learning Center NYC at City Tech
Brooklyn, NY
Bacterial Transformation
Bacterial transformation illustrates the direct link between an organism's genetics (genotype) and its observable characteristics (phenotype), and demonstrates how genetic engineering is used to produce human proteins such as insulin. In this lab participants will introduce genes for antibiotic resistance and fluorescence into the bacterium E. coli. Following overnight incubation, transformed bacteria can be compared to control bacteria for their ability to grow in the presence of ampicillin and glow when exposed to UV light.
Restriction Analysis
The DNA restriction analysis experiment demonstrates that DNA can be precisely manipulated with enzymes that recognize and cut specific target sequences. In this lab, restriction enzymes—the scissors of molecular biology—are used to digest DNA from the bacteriophage lambda. After cutting, the DNA fragments are visualized by agarose gel electrophoresis, allowing students to identify a “mystery” enzyme through comparison with controls.
These experiments directly correlate with lab requirements for AP Biology courses and align with the New York State Science Learning Standards, with an emphasis on analyzing and interpreting data, planning and carrying out investigations and the structure and function relationship. Guided by an experienced DNALC educator, training will focus on lab skills and conceptual connections.
There is no charge to attend. Participants may receive CTLE hours, if requested. Teachers will then be eligible to rent a footlocker kit from the DNA Learning Center to teach these labs in their classroom.

Dolan DNA Learning Center
Cold Spring Harbor, NY
The DNA Learning Center (DNALC) is offering a five-day, in-person workshop on DNA barcoding and metabarcoding. This free workshop is intended for science and nature enthusiasts, high school teachers, and science research teachers. High school teachers on Long Island interested in implementing authentic research experiences with students through Barcode Long Island (BLI) are welcome to apply. Trained mentors interested in a program refresher are also encouraged to attend. Science communicators and educators interested in bringing DNA barcoding outreach activities to their institutions are also welcome.
DNA Subway 2.0 is an educational platform that leverages research-grade bioinformatics tools and high-performance computing to create an intuitive experience for both students and educators. This workshop will provide participants with a walkthrough of the new version of the Blue Line, featuring a more modern and interactive interface with enhanced workflow tracking and data visualization.
Participants in this workshop will learn:
- Introduction to DNA barcoding, metabarcoding, and biodiversity
- Sample collection and documentation
- DNA extraction
- Polymerase chain reaction (PCR)
- Gel electrophoresis
- Bioinformatics–DNA Subway 2.0’s Blue Line
- Phylogenetics
- Program implementation
