Introduction to SARS-CoV-2

Coronaviruses are enveloped viruses with a positive-sense RNA genome and with a nucleocapsid of helical symmetry. Coronavirus nucleoproteins localize to the cytoplasm and the nucleolus, a subnuclear structure, in both virus-infected primary cells and in cells transfected with plasmids that express N protein. https://www.creativebiolabs.net/symbolsearch_2019-nCoV%20NP.htm
