DNA-based computing has been one of the few promises we have about the future of computing. As reported by The Register, a group of researchers from Incheon National University in South Korea has developed a rather basic processor made from DNA molecules, hoping to replace traditional electronics-based processors in the future.
The use of DNA molecules for computing has been mainly discussed as a storage medium. As biology and computer science came together, researchers have experimented with DNA molecules to create storage solutions that can hold terabytes of data with ease. However, this solution has a small problem. While the vast storage capacity of DNA-based solutions is a promising factor, it has a small limitation. Reading and writing to those data storage solutions takes up to a second for a single base to be written to DNA-based storage.
This is primarily due to the fact that DNA storage operates on a different principle and needs a different way to work with data. So a natural solution to this would be a processor based on DNA molecules that will operate on the same data formatting principle as the storage solutions accept. This is exactly what we are presented with today.
