Figure 2From: Base-By-Base: Single nucleotide-level analysis of whole viral genome alignmentsSection of a gene feature report comparing SARS coronavirus strains BJ03 and BJ04. The Base-By-Base table header describes the listed data. Since the non-structural proteins (NSP) that we have annotated in VOCs are fragments of the ORF1a and ORF1ab polyproteins, the length differences appear as negative numbersBack to article page
