The Science Behind DNA Storage

Understanding DNA as Data Storage

DNA, the blueprint of life, encodes genetic information using sequences of four nucleotides: adenine (A), cytosine (C), guanine (G), and thymine (T). These sequences can be synthesized to store binary data, transforming how we archive information. The University of Missouri researchers use frameshift encoding to convert binary data into DNA sequences.

How DNA Reads and Writes Data

The writing process in DNA storage involves synthesizing DNA strands with specific nucleotide sequences. Reading these sequences is equally innovative. Nanopore sensors detect electrical signals as DNA passes through, converting the sequences back into binary data. This process ensures data can be rewritten and erased, mimicking traditional hard drive functionalities.
