Towards the end of last term, Year 13 Biologists attended a DNA workshop at We the Curious Museum in Bristol. We sampled our own DNA from cheek cells to explain why some of us could taste a bitter compound known as PTC. Spinning our samples in a centrifuge, we separated the cells to obtain our DNA which we then amplified using the polymerase chain reaction – 35 billion copies each were produced! At each stage we learnt how to use micropipettes to transfer very very small quantities—down to 1/5 of the size of a raindrop!! The workshop was fascinating and we were able to apply what we’ve learnt this year.
Thanks to Mrs. Baker for organising the trip. And a shout-out to Mike from We the Curious!!
