BLAST Nucleotide Search
Search nucleotide sequences using NCBI BLAST blastn against nucleotide databases. Requires Biopython (pip install biopython). IMPORTANT: This tool uses NCBI's remote BLAST service which is inherently SLOW - expect 5-30 minutes per query depending on server load. This is normal NCBI behavior, not a bug. For faster results, use smaller databases like 'refseq_select_rna' instead of 'nt'.
