| The UW iGEM team is a very interdisciplinary group. Our team members span three faculties: Science, Mathematics, and Engineering, and represent a wide range of undergraduate programs: Biology, Biomedical Sciences, Biochemistry, Computer Science, Bioinformatics, Computer Engineering, Electrical Engineering, Chemical Engineering, Systems Design Engineering, and Mathematical Physics.
Drawing on our diverse backgrounds, we bring a wide range of skills and modes of creative thinking to our iGEM project. The iGEM competition is providing us with an opportunity to become more familiar with the emerging field of synthetic biology in an engaging and fun atmosphere. In addition to gaining experience in the design, construction, and analysis of genetic circuits, we are also meeting the challenge of bringing together a large, diverse group toward a common goal.
| The goal of this project is to design a basic device for computing. Our idea was to reproduce a circuit element called a half adder with DNA, which takes in two 1-bit inputs, adds them, and outputs a sum and a carry. Our device responds to two inputs: red light and the chemical tetracycline. The input sensors control a set of genetic switches in order to carry out the computation and fluoresces green, red, or neither, depending on the outcome.
Half adders are used as building blocks for full adders, which perform calculations similar to long addition but in binary. They are also an essential component in a device called the Arithmetic Logic Unit (ALU), a fundamental building block for the central processing unit in a modern computer. ALUs perform simple and complex operations such as bitwise logical operations and mathematical operations.
The constructs for the half adder were built in parallel as well as the testing constructs. A future extension to this project would be to create a full adder. More information on each stage of the project is available below.
