SARS-CoV-2 Mutation Mechanism, Features, and Future Perspective
Over two years, the SARS-CoV-2 virus has evolved by producing several variants by RNA polymerase mutation. This mutation created many virus variants that five of them are designated by WHO. These are Alpha, Beta, Gamma, Delta, and Omicron, among them Alpha, Delta, and Omicron spread faster. Coronavi...

| Sumario: | Over two years, the SARS-CoV-2 virus has evolved by producing several variants by RNA polymerase mutation. This mutation created many virus variants that five of them are designated by WHO. These are Alpha, Beta, Gamma, Delta, and Omicron, among them Alpha, Delta, and Omicron spread faster. Coronaviruses (CoVs) are enveloped in positive-sense RNA viruses and contain huge RNA virus genomes. RNA polymerase controls the replication in which the genomic material is copied, and it often makes errors that lead to create a new mutation. Most mutations create a virus that cannot replicate and spread among people. However, some mutations lead to a virus that can replicate and create a variant. This chapter will discuss the mechanism of the mutations during the last two years and the future of these mutations in SARS-CoV-2. |
