🧬 Python for Bioinformatics – Internship Update
The Python for Bioinformatics Internship is designed to help students build strong foundations in programming while applying it to real-world biological data analysis. This program focuses on combining Python skills with bioinformatics concepts such as DNA sequence analysis, string manipulation, and data processing.
Throughout the internship, participants will:
- Learn Python basics tailored for biological applications
- Work with DNA/RNA sequences using string operations
- Perform sequence analysis like GC content and base counting
- Handle bioinformatics file formats (such as FASTA)
- Build a mini project to apply their learning
Each task includes:
- 📺 Session-based learning
- 📝 Notes preparation
- 💻 Hands-on coding practice
- 📤 Submission via Google Forms
By the end of the internship, students will gain practical experience in computational biology and develop skills useful for careers in bioinformatics, data science, and research.
