🧬 Explore the Power of Restriction Enzymes!
See molecular biology in action with our Lambda DNA Electrophoresis Kit, using lambda DNA and restriction enzymes to demonstrate how DNA can be cut into different fragment patterns and separated by gel electrophoresis.
In this gel image:
🔹 Lanes 2 & 6 – Undigested lambda DNA (the original DNA sample)
🔹 Lanes 3–5 – Lambda DNA digested with EcoRI, HindIII, and BamHI, producing different banding patterns depending on where each enzyme cuts the DNA
Why are the patterns different? Each restriction enzyme recognises a unique DNA sequence and cuts at specific locations, creating fragments of varying sizes. This clearly demonstrates the specificity of restriction enzymes and how scientists analyse DNA using electrophoresis.
A fantastic hands-on way to bring genetics and biotechnology to life in the classroom!
