Gene annotation (source code)

= Gene annotation

<Gene annotation> identifies the structure and attributes of a <gene> in a reference sequence. It records features such as <exons>, splice forms and coding regions, often combining <RNA> evidence with sequence comparison. A supported transcript structure does not automatically establish a known biochemical function for its product. Distinguishing structural evidence from functional interpretation prevents a prediction from being mistaken for a fully characterized <gene>. <Genomic annotation documentation by the National Library of Medicine>[Nucleotide sequence and genome annotation: gene annotation]{ref}
