Introduction DNA is a natural storage source
“The total world's information, which is 1.8 zettabytes, [could be stored] in about four grams of DNA”
A lot of information in one, small location

How does it Work?
Message or Information in Binary is Encoded into A, C, G, and T
DNA is synthesized from the A, C, G, T encoding
DNA sequence of A, C, G, and T is inputted on the synthesized DNA
Finally, the A, C, G, T is decoded back to binary so it can be read by a computer

Advantages Miniscule in size, not in storage capabilities
Longevity
Durable
Archival Storage
No Electricity

Disadvantages Only manufactured in short strings
Writing and reading DNA is prone to errors
Retrieval takes a long time Archival purposes ONLY

Disadvantages cont. Price
Activity Cost (per megabyte)
Information Storage $12,400
Information Decoding $220

Why Choose DNA? “All we're doing is adapting what nature
has hit upon—a very good way of storing
information”
Technology is advancing
Advantages are sizable and disadvantages
are temporary
