WebViral evolution. Viral evolution is a subfield of evolutionary biology and virology that is specifically concerned with the evolution of viruses. [1] [2] Viruses have short generation times, and many—in particular RNA viruses —have relatively high mutation rates (on the order of one point mutation or more per genome per round of replication). WebA second mutation in the gene coding for the spike protein responsible for recognizing the ACE2 receptor on the host cell. This mutation makes the spike proteins a different completely different shape. A mutation in the gene that codes for the enzyme that copies the RNA genome of SARS-CoV-2.
