Damn. That's the weight of a paper clip.
🧬 DNA is the most compact and efficient data storage system known. Just one gram of DNA can theoretically hold up to 215 petabytes of data — that's 215 million gigabytes.
DNA’s potential as a data storage medium lies in its molecular structure and information density. Each strand of DNA is composed of four nucleotides — adenine (A), thymine (T), cytosine (C), and guanine (G) — which can be used to encode digital data by mapping binary sequences to base pairs (e.g., 00 = A, 01 = C, etc.).
Because DNA is nanoscale, its information density is extraordinarily high.
DNA's molecular stability allows it to preserve information for millennia if kept in suitable conditions (cool, dry, dark environments). Unlike magnetic or optical storage, DNA doesn't degrade rapidly and doesn’t require constant energy input.
