Cluster of orthologous groups是什么

WebDec 26, 2024 · The Clusters of Orthologous Genes database was introduced in 1997 to provide evolutionary classification of protein families. COG is a relatively small, but manually curated and, thus, high-quality orthology resource. Orthologous groups are constructed by considering bidirectional best hits of sequences comparing complete genomes. http://docs.apps.blast2go.com/blast2go-apps/orthologous-groups/
