Mapping the mutations from the West Bengal variants, double mutant (B.1.617) and triple mutant (B.1.618), onto X-ray crystallographic structure of Receptor Binding Domain (RBD) and Cryo-EM structure of the Spike protein. Amino acids positions of E484K, D614G, and Y145-H146 are highlighted. The 3-minutes video is presented in Thai but I have provided a closed caption in English at this YouTube link (https://www.youtube.com/watch?v=vjmkRuJ-B8A)
