These free, online Agricultural Biotechnology course materials from Futurelab+ make up a 36-week course that investigates "the amazing ways that living organisms can be harnessed to improve agriculture processes and redefine a healthier relationship with the natural environment." The course consists...

In the early days of DNA manipulation, DNA fragments were laboriously separated by gravity. In the 1970s, the powerful tool of DNA gel electrophoresis was developed. This process uses electricity to separate DNA fragments by size as they migrate through a gel matrix. This animation from Cold Spring...

This lab activity from the Biotechnology Alliance for Suncoast Biology Educators (BASBE) introduces the methods of RFLP analysis, or DNA fingerprinting, by using gel electrophoresis. Students will learn the role of restriction enzymes in DNA fingerprinting. Required materials, procedure and...

This lab activity from the Biotechnology Alliance for Suncoast Biology Educators (BASBE) provides instructions for conducting a gel electrophoresis lab. Students will try to solve a paternity case with this activity by obtaining a DNA fingerprint from each potential father, the mother and the child....
