Abstract
:
In the information age, data storage technology has become the key to improving computer
systems. Since traditional storage technologies cannot meet the demand for massive storage, new DNA
storage technology based on biomolecules attracts much attention. DNA storage refers to the technology
that uses artificially synthesized deoxynucleotide chains to store and read all information, such as documents,
pictures, and audio. First, data are encoded into binary number strings. Then, the four types of
base, A(Adenine), T(Thymine), C(Cytosine), and G(Guanine), are used to encode the corresponding binary
numbers so that the data can be used to construct the target DNA molecules in the form of deoxynucleotide
chains. Subsequently, the corresponding DNA molecules are artificially synthesized, enabling
the data to be stored within them. Compared with traditional storage systems, DNA storage has
major advantages, such as high storage density, long duration, as well as low hardware cost, high access
parallelism, and strong scalability, which satisfies the demands for big data storage. This manuscript
first reviews the origin and development of DNA storage technology, then the storage principles, contents,
and methods are introduced. Finally, the development of DNA storage technology is analyzed.
From the initial research to the cutting edge of this field and beyond, the advantages, disadvantages, and
practical applications of DNA storage technology require continuous exploration.
