DNA (deoxyribonucleic acid), could also be called the “source code” of life on Earth. Whereas machine code relies on a binary alphabet of 0s and 1s, DNA relies on a quaternary code of the ATCG nucleotides. DNA is easy to read from, write to, and copy, since these functions are already implemented by natural cellular machinery. In addition, it is very stable, and does not require much energy to store. Due to these advantages, it has recently become a medium of interest for long-term information storage. 
One flaw of DNA as a storage medium is that information stored in DNA can be corrupted through point mutations.  In particular, mutations can involve a nucleotide being removed from the DNA sequence (deletion), a nucleotide being changed to a different nucleotide (substitution), or a new nucleotide being added at an arbitrary location (insertion). If DNA is to be used as information storage, there is a need for error-correcting codes which can reliably handle all three types of error.
In this project, I implement a code presented in a recent paper  that corrects a single edit (substitution, insertion, or deletion) with redundancy. In other words, to correct a single edit in a message of symbols, only additional symbols need to be used. In contrast, previous approaches had a redundancy of where .
The implementation and a high-level explanation of how the code works can be found at this GitHub repository. The code is intended to be open-source and may be freely used, reproduced or modified with suitable accreditation.
