# Public Samples

Practise identifying bacterial species using different types of 16S rRNA sequences provided below. 

### FASTA

A commonly used text-based format for representing nucleotide or protein sequences, where each sequence is preceded by a single-line description starting with a '>' symbol.

### AB1

A binary file format from Applied Biosystems DNA sequencers that stores DNA sequencing chromatogram data, including the raw signal intensity and quality scores for each base call.
