I have a set of 900 FASTA sequences that were differentially expressed during a specific stimulation related to synaptic plasticity. Using Biopython, I performed a BLAST search via NCBI and shortlisted 5 key hits. Now, I want to categorize these sequences based on their functions or activities. Would Gene Ontology (GO) analysis be a suitable approach for this? As someone new to both bioinformatics and Biopython, I would appreciate guidance on how to start and which tools or databases to use. Thank you
