Description
⚡ DNA fragments racing through jelly? That’s basically gel electrophoresis.
Stanley walks us through this super-short practical, showing how scientists separate DNA by size using an electric current in the labs at the Wellcome Sanger Institute - one of the core techniques you need for A-Level Biology, genetics, DNA profiling, and biotechnology. 🧬
Perfect for:
- Quick revision
- Required practicals
- Visual learners
- Last-minute exam prep
Smaller fragments move further. Negative DNA moves to the positive electrode. Bands reveal the results. Simple — but massively important in modern biology.
Watch it once before your exam and the process actually sticks.
