Mutational cascade of SARS-CoV-2 leading to evolution and emergence of omicron variant

K Bansal, S Kumar - Virus Research, 2022 - Elsevier
Background Emergence of new variant of SARS-CoV-2, namely omicron, has posed a
global concern because of its high rate of transmissibility and mutations in its genome.
Researchers worldwide are trying to understand the evolution and emergence of such
variants to understand the mutational cascade events. Methods We have considered all
omicron genomes (n= 302 genomes) available till 2nd December 2021 in the public
repository of GISAID along with representatives of variants of concern (VOC), ie, alpha, beta …
