DNA Seq

A lightweight Python application for DNA sequence analysis, supporting real-time transcription, translation, and visualization. Designed for students, researchers, and developers exploring bioinformatics fundamentals.

Features

DNA → RNA Transcription

• Converts raw DNA sequences into RNA in real time
• Handles uppercase/lowercase input, invalid base filtering, and edge-case sequence validation

RNA → Amino Acid Translation

• Implements codon-to-amino-acid mapping
• Supports full-chain amino acid output (including stop codons)
• Permits partial-codon handling for live input

Real-Time Visualization

• Uses OpenCV to detect nucleotide-colored markers in live video feed
• Matches detected color regions to corresponding nucleotides (A, T, C, G)
• Allows hands-free DNA input via visual cues

Bioinformatics Logic

• Efficient string parsing for large sequences
• Clean modular structure (transcription, translation, visualization separated)

Tech Stack

• Python 3
• OpenCV for real-time color detection
• NumPy (optional)
• Custom codon tables and parsing logic
