DNA Data Storage: Myths and Realities

Recently, impressive research results on DNA data storage have been published in Nature. Although DNA exists in nature, it can also be synthesized in the form of oligonucleotides in vitro, so there have been several studies to store information in DNA. The difference between this study and previous studies is that it has succeeded in storing and retrieving very short videos in live bacteria using the latest gene editing technology CRISPR-Cas system. The lower left is the original image and the right is the image taken from the E. coli DNA, indicating that the data content is almost complete. The data recovery rate is about 90%.

With this wonderful result being released, interest in the area of DNA computing and data storage is growing. Some say that DNA computing is the future, and commercialization is on the horizon. However, there are many obstacles to overcome in order for th…
