Novel Coronavirus

Puca Edmond

 Corona virus have an unsegmented, single-stranded, positive-sense RNA genome of around 30 kb, encased by a 5′-cap and 3′-poly(A) tail. The genome of SARS-CoV-2 is 29,891 bp long, with a G+C substance of 38%. These infections are surrounded with an envelope containing viral nucleocapsid. The nucleocapsids in CoVs are orchestrated in helical balance, which mirrors an atypical quality in certain sense RNA infections. The electron micrographs of SARS-CoV-2 uncovered a wandering round layout with some level of pleomorphism, virion breadths fluctuating from 60 to 140 nm, and unmistakable spikes of 9 to 12 nm, giving the infection the presence of a sun oriented crown.
