Yes. Researchers can encode file data into sequences of DNA bases, synthesize those molecules and recover the data by sequencing them. The approach suits research into long-term archives rather than ordinary computer memory.
A molecule can carry a symbolic code
Digital files contain patterns of bits. DNA contains a sequence drawn from four bases, commonly written A, C, G and T. An encoding scheme translates one pattern into the other. Reading the sequence and applying the decoding rules can reconstruct a file. The DNA need not be part of a living cell.
A real experiment stored and recovered files
EMBL-EBI researchers demonstrated recovery of encoded text, an image and other file types. Their method used short fragments and redundancy to manage errors. That is a laboratory demonstration of digital storage, not merely a claim that biological DNA already contains information. [1,2]
Why density is not the whole comparison
Imagine an extremely compact library with a very slow librarian. It could be excellent for preserving material you rarely request, yet poor for constantly changing documents. DNA storage has a similar tradeoff: synthesis and sequencing are separate laboratory operations. A striking density estimate does not tell you the price or delay of reading one specific file.
What an archive would need to preserve
The molecules are only one part of the system. A future reader also needs the encoding convention, ordering information and a reliable way to read the bases. Error correction helps account for missing or misread fragments. Good storage design preserves both the data and the instructions needed to interpret them, just as keeping a computer file is insufficient if its format is forgotten.
Frequently asked questions
Does the DNA need to be alive?
No. Synthetic DNA fragments can carry encoded files.
Can DNA replace RAM today?
The demonstrated archival approach does not behave like fast computer RAM.
Can a DNA sequence contain a photograph?
A coding scheme can represent the digital file for a photograph.
