Bioinformatics Core Toolkit

A Python-based toolkit developed for the implementation and exploration of fundamental bioinformatics workflows, including DNA sequence analysis, FASTA file parsing, mutation detection, and DNA-to-protein translation.

Project Overview

The increasing integration of computational methods into biological research has made bioinformatics an essential component of modern life sciences. This project was developed as a foundational exercise in applying Python programming to biological sequence analysis and computational biology.

The toolkit implements a collection of commonly used sequence-based operations and serves as a basis for future extensions in genomics, molecular biology, and data-driven biological research.
