D614G mutation—molecular structure of the #SARSCoV2 spike protein with the D614G mutation, which allows it to attach to cells easier. Although it’s a mutation compared to Wuhan 1.0, this is already the predominant “common” version being replaced by #B117. pnas.org/content/pnas/1… 
2) The spike protein is found on the surface of the virus and is responsible for its ability to attach to and invade human cells. The D614G mutation first appeared in Summer 2020 and the strain with this mutation quickly became dominant around the world.
3) The researchers found that this mutation changes the structure of the spike protein, allowing it to more readily attach to cells.
4) We had suspected variant with D614G was more contagious for a while. And again; this is now already the common circulating type that is now being further displaced by #B117 UK variant. B117 is more contagious than the D614G contagious variant. Crazy.
