DNA Sequence Analyzer

A simple Python tool for analyzing DNA sequences. This program converts DNA sequences to RNA and then to proteins, providing an easy way to work with basic DNA-to-protein transformations.

Features

• Converts a DNA sequence to RNA.
• Translates RNA to a protein sequence.
• Checks for valid DNA sequences (ensures only 'A', 'T', 'C', and 'G' bases are used).

Requirements

• Python 3.7+

• Biopython: This library is used for handling biological sequences. Install it via pip:

  pip install biopython

Usage

1. Clone the repository:

   git clone https://github.com/sha23di/DNA_Sequence_Analyzer.git cd DNA_Sequence_Analyzer

2. Run the script:

   python dna.py

3. Enter a DNA sequence when prompted. The program will validate the sequence and then display the corresponding RNA and protein sequences.

Example

Welcome to the DNA Sequence Analyzer Enter a DNA sequence: ATGCGTAC

Results: DNA Sequence: ATGCGTAC RNA Sequence: AUGCGUAC Protein Sequence: MR

Functions

• dna_to_rna(dna_sequence): Converts a DNA sequence to an RNA sequence by transcribing it.
• rna_to_protein(rna_sequence): Converts an RNA sequence to a protein sequence by translating it.
• is_valid_dna(dna_sequence): Checks if a sequence contains only valid DNA bases ('A', 'T', 'C', 'G').
