Extracting DNA in Year 12 Biology

For their first prac of the term, our Year 12 Biology class were in the ASMS lab extracting DNA from fruit.


Our students started off by cutting up banana, strawberries, and kiwi fruit, then added an extraction buffer, and mashed the samples to create their fruit mixtures.

They then sieved each one through a filter and were left with three fruit mixtures to extract DNA from.

After that, they slowly added alcohol into the mixture, which caused the DNA to separate so that it could be removed and examined under a microscope.

Not only was this a fun way to kick off the term, but it was also a fantastic opportunity for our Year 12s to be hands-on with their learning!
