WebDec 19, 2024 · It is a non-enveloped virus with an icosahedral capsid structure generated from three capsid proteins (VP1, VP2, and VP3) . The capsids contain a single-stranded DNA (ssDNA) genome of 4.7kb that carries two genes, rep and cap, flanked by palindromic inverted terminal repeat WebThe virus core contains the genome—the total genetic content of the virus. Viral genomes tend to be small, containing only those genes that encode proteins which the virus cannot get from the host cell. This genetic material may be single- or double-stranded. It may also be linear or circular.
