NCBI Get Sequence

Retrieve DNA/RNA sequence data from NCBI by accession number. Returns sequences in specified format (fasta, gb, embl). Works with both EMBL/GenBank accessions (U00096, M15390) and RefSeq accessions (NC_045512, NM_000546). Use this to get actual sequence data after finding accessions with NCBI_search_nucleotide. Returns full sequence with annotations depending on format.
