Synthetic biology can be used to create biofuels, therapeutics, biosensors, and bioremediation. This often involves introducing new DNA into an existing organism. However, at the same time, it is important to also develop genetic safeguards to ensure that this new DNA is not unwillingly transferred to another organism. One safeguard is to create an organism lacking key DNA repair enzymes (UNG and DUT) that are responsible for fixing misincorporated uracil in the genome. Therefore, this organism will accumulate uracil mutations in its genome, and if it mates with another organism the uracil mutated genome will be recognized as faulty and destroyed. The Synthetic Biology in action participants describe these different safeguarding mechanisms and how they created a host organism with UNG and DUT deletions.
