What iGEM is All AboutThe International Genetically Engineered Machines (iGEM) Competition is an annual undergraduate research competition hosted by MIT. The project aim is to develop Synthetic Biology through the creation of an open registry of parts, or biobricks. Each part in the registry is an analyzed strain of DNA with several specific restriction sites at each end of the fragment. These strains can be anything from promoters to genes, allowing easy assembly and reassembly of these parts into genetic circuits. The [2007 Jamboree] consisted of 54 teams from 19 countries who presented their findings. Penn State's 2007 iGEM project: Diauxie EliminationPenn State won a Gold medal in the 2007 iGEM Jamboree! We're proud of our work during the year and our registry submissions. Abstract:Increasing energy demands have brought about the need for a renewable, efficient energy source.
