DNA Part 2: DNA replication and how errors can become mutations.

This video, in combination with our DNA part 1 video, gives a good overview of DNA for A-level biology students. There is then a fun at home science experiment you can do in DNA part 3. This video covers DNA replication and how errors in replication can become mutations. We will then look at cystic fibrosis as an example of a genetic disease and how mutations in a gene impact the corresponding protein and how this relates to disease symptoms.
