Vincent 13:42, 6 June 2007 (EDT): feel free to comment on the content of the activity described and its design.
Context
- Following last year Imperial College participation to iGEM, my group is putting together an exhibit for the Royal Society Summer Science Exhibition 2007.
- We feel it is a great opportunity to engage with the Public on the concepts behind Synthetic Biology.
- The exhibit attracts a diverse audience from school kids to science enthusiasts.
- I have started to design a hands-on activity, and describe its early design below.
Intentions behind the activity
- To set the background in terms of Molecular and Celluar Biology:
- DNA, Central Dogma, Cells and Bacteria
- Genetic Engineering techniques
- To touch on Synthetic Biology concepts:
- BioBricks
- Modularity
- Re-usability
- To give an opportunity to build simple genetic circuits based on opto-electronic components:
- Protein Generator
- Inverter, Toggle switch & Repressilator
- Link circuits with inputs such as: temperature sensor, Infra-red sensor, Touch sensor, Humidity sensor.
- Link circuits with outputs such as: flagella motor, secretion fan.
