In this video we look at the two ways in which we can produce fragments of DNA by using enzymes:

- Reverse Transcriptase
- Restriction Endonucleases

Made for AQA A2 Level Biology Students studying Unit 5.

These videos are great. I can never thank you enough. If you can can you make videos on the whole chapter for DNA? That would be fantastic. Thanks for the videos so far!

It may be a bit late, but do you think you could squeeze in a gene therapy video or DNA fingerprinting
