highly prone to mutation, partly because the replication enzymes of RNA viruses make more mistakes when copying genetic material.Although the virus is mutating slowly, scientists had raised concerns that some of the mutations could make the virus more infectious.One mutation in particular – D614G – has been a focus of concern, as it occurs in the spike protein of the virus.
This site is important because it is the spike protein that attaches to host cells and eventually leads to their infection.
