Gel Electrophoresis of DNA
Produced by Science & Plants for Schools (SAPS), this activity enables students to look at the gel electrophoresis of DNA treated with restriction enzymes. It will help to develop a knowledge and understanding of the cutting of DNA with restriction enzymes.
In the experiment, a batch of DNA is digested by two different restriction enzymes. The fragments are separated by gel electrophoresis and the difference in patterns analysed.
The investigation is designed for students following a Scottish Highers course but it is equally useful for other post-16 courses in biology. It could also be adapted for younger secondary school students.
