Edvotek Biotechnology – Restriction Enzyme Analysis of DNA (Code 80424)

The Edvotek Restriction Enzyme Analysis of DNA kit introduces students to one of the core techniques in modern molecular biology: the use of restriction enzymes to cut DNA at specific nucleotide sequences. This foundational biotechnology experiment demonstrates how DNA can be precisely fragmented and analysed to reveal its structure.

Students work with bacteriophage lambda DNA, a linear DNA molecule containing multiple EcoRI recognition sites. When the DNA is digested with the EcoRI restriction enzyme, it is cut into several fragments. These fragments are then separated using agarose gel electrophoresis, allowing students to visualise distinct DNA banding patterns.

The resulting gel typically shows six bands (five clearly distinct bands, with two very close in size), providing a clear demonstration of how restriction enzymes generate predictable DNA fragment patterns used in genetic analysis and biotechnology applications.
