NCBI Search Nucleotide

Search NCBI Nucleotide database (GenBank/EMBL/RefSeq) by organism, gene name, or keywords. Returns GenBank UIDs which can be used to fetch accession numbers. Supports filtering by organism, gene, strain, sequence type (complete genome, mRNA, RefSeq). Use this to discover DNA/RNA sequences for specific organisms or genes. Returns both EMBL/GenBank accessions (U00096, M15390) and RefSeq accessions (NC_*, NM_*). Follow up with NCBI_fetch_accessions to get actual accession numbers.
