Scientists are working on storing digital data in the base sequence of DNA (Deoxyribonucleic acid) . They are looking for to make the genetic material capable to store data for long time in durable format as a store data for the future.

Sequence of DNA (Deoxyribonucleic Acid)

DNA: Information-storing molecule

  • DNA is abstract an information-storing molecule.
  • It brings the genetic instructions used in the growth, operative, development and reproduction of all known living.
  • By the genes genetic instructions are passed from generation to generation.
  • DNA mainly transmits the blueprints for creating the human body.

How DNA store information?

  • Information in the DNA is stored in strings in the form of four-letter DNA code.
  • It is fundamentally sequences of four building blocks (nuclear strands) abbreviated as:
    • A (Adenine)
    • C (Cytosine)
    • T (Thymine)
    • G (Guanine)
  • These are found in DNA molecule.
  • For creating particular proteins, specific sequences of these blocks give the body directions.

How DNA can transfer Digital information?

  • In binary format (1s and 0s) digital devices store information that is in a two-letter code that produces strings of 1s and 0s.
  • For ex. capital ‘A’ stored as 01000001 in binary format.
  • In case of storing and converting digital information in DNA includes transforming between the two sequences or codes of four building blocks. For ex. capital ‘A’ converted and stored as AATATG.
  • For the storage DNA digital data storage technology uses artificial DNA made using oligonucleotide synthesis machines.
  • DNA sequencing machines uses for retrieval of stored data.
  • Using this technology strings of DNA can be custom-made.
  • That can carry the new code and store information that code includes.

Benefits:

  • DNA digital data storage technology has very extended durability.
  • Thousands of years, scientists can store digital information in DNA sequences
  • DNA consumes information is stored in very little space.

Challenges:

  • Current technology is hugely expensive. So, making this technology practical and much cheaper.
