I would request your help in finding an image of a all sars-cov variants and their cleavage site.
Interestingly, you can see the stepping pattern. I have a hazy recollection that Vanden Bossche and or Del Bigtree showed it on video.
If you have it per chance, or know where I can find it, please, post the link or let me know below
Oh. That cleavage .Carry on.
