How does DNA encode data?

Published in DNA Encoding 2 mins read

DNA encodes data by converting arbitrary data into a specific nucleotide sequence. The process typically involves first transforming the data into a ternary (base 3) format.

Encoding Data in DNA: A Step-by-Step Guide

Here's a breakdown of how data is encoded into DNA, leveraging the information from the provided reference:

  1. Data Conversion to Ternary: The initial step involves converting the data, which is often in binary format (base 2), into ternary (base 3) data. This means the data is represented using digits 0, 1, and 2, rather than just 0 and 1.

  2. Ternary Digit to Nucleotide Conversion: Following the ternary conversion, each digit (also known as a "trit") is mapped to a specific nucleotide using a lookup table. DNA consists of four nucleotides: Adenine (A), Guanine (G), Cytosine (C), and Thymine (T). A simple example could be:

    Trit Nucleotide
    0 A
    1 G
    2 C

    In this scenario, if you have a ternary sequence "012", it would be encoded as "AGC" in DNA.

  3. DNA Synthesis: The synthesized DNA strand, now containing the encoded data, can be stored or used for various purposes.

This method, outlined in the reference, allows for arbitrary data to be stored within DNA sequences by using a system to convert and encode data into the four nucleotide bases.
