Sequence homology

sequence homology

(Science: molecular biology) Strictly, refers to the situation where nucleic acid or protein sequences are similar because they have a common evolutionary origin. Often used loosely to indicate that sequences are very similar. Sequence similarity is observable, homology is an hypothesis based on observation.
