Viral genomic fingerprints allow tracking over time and region The mutational history led to a collection of genetic fingerprints extending from the progenitor CoV to the current strain. Each is named for the major variants included. Both this progenitor genome and its branches have since led to an array of lineages or strains, some of which (e.g., D614G) have rapidly ascended to global or regional dominance in a very short time. The North American strains have all belonged to the same lineages for the major part of the pandemic period. These were mostly αβ along with its mutant (αβγδ), which has remained dominant Αυγούστου 14, 2021 Διαβάστε περισσότερα
