RefSeq

RefSeq, short for Reference Sequence, is a comprehensive collection of standardized DNA, RNA, and protein sequences maintained by the National Center for Biotechnology Information (NCBI). It provides unique, well-annotated reference sequences for genes and genomes, serving as a reliable baseline for scientific research, genetic analysis, and clinical diagnostics. Think of it as an authoritative library of genetic "blueprints" that helps scientists identify, compare, and understand genetic information across different organisms and individuals in a consistent way.
