Genetics of SARS-CoV-2

The genetics of SARS-CoV-2 has been controversial due to the debates over gain-of-function research and the origins story of the virus that led to COVID-19 pandemic policies.

Genetic RNA Structure


Early analysis of the genetics of SARS-CoV-2 which included examination of relative synonymous codon usage (RSCU) showed greatest similarity of genetic information with bat CoVs, but had most similar codon bias usage with snakes.1)

  • Analysis of SARS-CoV-2 synonymous codon usage evolution throughout the COVID-19 pandemic2)


Specific Sequences


  • Gain-of-Function Smashing Success: The Key Sequence Inserted in the SARS-CoV-2 Virus Added at Least *FOUR* Distinct Functions. Coincidence?3)

SEB Insert

Researchers found that that a monoclonal antibody against SEB inhibits SARS-CoV-2 entry in vitro.4) It is interesting to note that the preprint of this paper was uploaded on November 24, 2020, but went unpublished for more than 9 months.
