Global DNA sequence alignment App

I’m a biologist and this is my first webapp.

I’m interested on Data Science and on Bioinformatics and now I’m using Streamlit to try to learn some bioinformatics algorithms.

This app aligns two DNA sequences based on Needleman-Wunsch algorithm.

The scoring scheme was:
Match: reward of +1
Mismatch: penalty of -1, if transition
Mismatch: penalty of -2, if transversion
Gap: penalty of -3

Feedbacks are welcome!
