 These features are the backbone, the receptor binding domain, the furin cleavage site, the genetics of the furin cleavage site, the number, location, and pattern of cloning sites in SARS-2 that use the Baric cloning method and the ORF8 gene. Based on SARS-2 cloning sites, I predicted how SARS-2 could be made in the laboratory. A year later, Baric used the predicted steps to make an infectious clone of SARS-2.
