Fully in vitro iterative construction of a 24 kb-long artificial DNA sequence to store digital information
Résumé
In the absence of a DNA template, the production of long double-stranded DNA molecules of predefined sequences is particularly challenging. The DNA synthesis step remains a bottleneck for many applications such as functional assessment of ancestral genes, analysis of alternative splicing or DNA-based data storage. In this report we propose a fully protocol to generate very long double-stranded DNA molecules starting from commercially available short DNA blocks in less than 3 days using Golden Gate assembly. This innovative application allowed us to streamline the process to produce a 24 kb-long DNA molecule storing part of of 1789 . The DNA molecule produced can be readily cloned into a suitable host/vector system for amplification and selection.
