Genomic Encryption of Digital Data Stored in Synthetic DNA

Optimization of the genomic DNA extraction in some mosses

The presence of organic compounds and high amount of secondary metabolites (polysaccharides, phenolic component, etc.) in mosses cause difficulties in DNA extraction that are followed by problems in PCR reactions. In lower plants, various methods have been used for DNA extraction including silica gel and different commercial kits. These methods mostly use hazardous (like phenol or liquid nitrog...

Synthetic viability genomic screening defines Sae2 function in DNA repair

DNA double-strand break (DSB) repair by homologous recombination (HR) requires 3' single-stranded DNA (ssDNA) generation by 5' DNA-end resection. During meiosis, yeast Sae2 cooperates with the nuclease Mre11 to remove covalently bound Spo11 from DSB termini, allowing resection and HR to ensue. Mitotic roles of Sae2 and Mre11 nuclease have remained enigmatic, however, since cells lacking these d...

Binary DNA Nanostructures for Data Encryption

We present a simple and secure system for encrypting and decrypting information using DNA self-assembly. Binary data is encoded in the geometry of DNA nanostructures with two distinct conformations. Removing or leaving out a single component reduces these structures to an encrypted solution of ssDNA, whereas adding back this missing "decryption key" causes the spontaneous formation of the messa...
