Annotation data

Definition

Annotation data refers to the information added to genomic sequences that provides context and meaning, enhancing the understanding of the biological significance of the data. This can include details about gene function, regulatory elements, variations, and relationships between different genomic features. Such data is essential for effective interpretation in genomic research and is often integrated into genomic databases and resources.
