The whole world right now is concerned (or they should be) about the appearance of new variants of SARS-CoV-2. Among other things, these variant viruses have mutations that change the amino acid sequence of the spike protein on the virus surface. While this is concerning, I would like to propose that there is a limit to how far these mutations can change the spike protein. Why can't there be an endless number of new mutations of this viral protein? How would these amino acid changes affect how the virus works?Second letter A G UCU UCC UAU. Tyr UAC. UUU1 Phe UUC.
