SARS-CoV-2 spike glycoprotein SRWM insert at the N-terminal domain. Header of a fragment the SARS-CoV-2 spike glycoprotein multiple sequence alignment including the reference sequences [22] and sequences identified with the S247 SRWM insert (coordinate based on reference sequence) at the N-terminal domain. The total number of sequences in the multiple alignment is 331, however, for simplicity the figure only shows a part. Sequence are identified by SARS-CoV-2 GenBank genome accession and S gene coordinates. The insert is highlighted in yellow. At the top, the reference sequences are shaded in grey. Dashes denote gaps. The numbers on the right indicate sequence position
