This project is a simple DNA sequence viewer with a graphical interface powered by Python’s Tkinter and Biopython. It allows users to fetch and analyze DNA sequences from the NCBI database using a GenBank accession number.

Features:

• GUI Application: gui.py provides an interactive interface for users to enter accession numbers and fetch DNA sequence details.
• Sequence Fetching: The fetch_sequence.py script uses Biopython’s Entrez module to retrieve sequences, displaying key information like sequence length and GC content.

Usage:

1. Install Python 3.x and Biopython (pip install biopython).
2. Run the GUI application (python gui.py).
3. Enter a valid GenBank accession number to retrieve DNA sequence information.

This project is suitable for beginners in bioinformatics looking to interact with genomic data.
