Viral sequencing, phylogenetic analysis, and synonymous codon usage analysis of ZJ01. (A) Due to an accident during sequencing, the ORF1ab segment of the ZJ01 sample lost a 0.5 k base during this study. (B) The amino acid sequence alignment of ZJ01 shows that it is nearly identical with the Wuhan SARS‐CoV‐2 in S protein. (C) A three‐dimensional reconstruction model of the S protein clearly shows where the mutations are located. (D) Maximum likelihood genealogy shows the evolution of SARS‐CoV‐2. It reveals the relationship between SARS‐CoV‐2 and other coronaviruses. (E) Results from the RSCU heat map demonstrate that the RSCU of ZJ01 appears to be moving away from its relatives
