Year 12 Makes DNA

Year 12 Bio have been working like absolutely superstars towards their upcoming practice NCEA exam. We have finally covered all of the content (there was a LOT!) and now they are ready to revise and refresh.

On Monday and Tuesday we made lolly models of DNA, and then used them again to demonstrate DNA replication. It seemed to work quite well, and I hope the class enjoyed getting in there and making the models for themselves. 

We used liquorice as the 'sugar' part of the backbone, and added marshmallows as the 'phosphate' - that was the best that we could do for the backbone of the double helix! 

Then we added wine gums as the four bases, making sure to only pick 4 colours of wine gums and only pair them with their 'complimentary base pair.' 

Here's an example of the finished product. :) 

My next post will be some top tips for how to study and revise for exams, both online and off!
