Fig. 1From: Analysis of SARS-CoV-2 RNA-dependent RNA polymerase as a potential therapeutic drug target using a computational approachDendrogram representing the phylogeny of viruses with SARS-CoV-2. Phylogenetic tree is divided into three clades, and all clades are further divided into sub-groups. 2019-SARS-CoV-2 from clade III is closely related to its relatives from Hong Kong and USA (circled in blue).
