The genome of SARS-CoV is 29,727 nucleotides in length, and the genome organization is similar to that of other coronaviruses.
Their size is highly variable with average diameters of 80 to 120 nm. When a retrovirus infects a cell, it makes a DNA copy of its genome that is inserted into the DNA of the host cell. The virion structure consists of an outer envelope, the core, nucleoprotein and a nucleocapsid. Coronaviruses have enveloped virions that measure approximately 120 nm in diameter. SARS-CoV-2 is the seventh coronavirus that has humans as the host. 2020).The first ORF comprises approximately 67% of the genome that encodes 16 nonstructural proteins (nsps), whereas the remaining ORFs encode for accessory and structural proteins. Nucleotides are organic molecules that form the structural unit building block of nucleic acids, such as RNA and DNA.
