The researchers claimed that their approach allowed them to characterize emerging mutations such as the British variant B.1.1.7 smoothly and swiftly.
The study, published in the journal Nature, stated that the D614G variant of coronavirus carries a mutation in the spike protein that makes it easier for the virus to cling onto human cells.
