🧬 Binary → DNA → ASCII Decoder

This project demonstrates a fun and unconventional encoding/decoding pipeline:

Binary → DNA bases (A, G, C, T) → ASCII text

It is inspired by DNA/genome-based encoding techniques often seen in CTFs, steganography challenges, and bio-inspired computing puzzles.

📌 Overview

The script reads a binary string from a file (dna.txt) and decodes it in two stages: 1. Binary → DNA • Each 2-bit binary chunk is mapped to a DNA base. 2. DNA → ASCII • Every 3 DNA bases (a codon) are mapped to readable characters using a predefined codon table.
