Genetic Engineering a 9m 24s video, Genetic Engineering for AQA GCSE (9m) and Genetic Engineering for Edexcel GCSE (15m), Genetic Engineering & Clones, a 15m video from The Virtual Body.

3.5 Genetic Modification & Biotechnology

IB Biology 3.5 genetic modifcation and biotechnology from Bob Smullen

An animated, narrated tutorial on Gel Electrophoresis which also includes a quiz (from Sinauer Associates); and here is a video tutorial from Stephanie Castle:

For Gel Electrophoresis & DNA profiling – click on ‘Restriction Digestion & Gel Electrophoresis’ to see an Interactive Animation from Wiley or here for fantastic animated tutorials from McGraw Hill Education – DNA fingerprinting & Restriction fragment length polymorphisms (RFLPs) or how about a 5m27s lesson from Naked Science Scrapbook: how does DNA fingerprinting (DNA profiling) work?. Or, finally, Paul Andersen describes the process of DNA Fingerprinting and DNA profiling.

How to set up and run a Gel electrophoresis (for DNA profiling):

For Gene Transfers (genetic modification) see these fantastic animated tutorials from McGraw Hill Education – Restriction Endonucleases, steps in Cloning a gene & construction of a Plasmid vector or click on ‘Cloning’ to see an Interactive Animation from Wiley.

An animated, narrated tutorial on human embryonic stem cells (from Sinauer Associates).
