Note that a virus is classified according to the following things in sequence:

  • DNA/RNA virus

  • Capsid symmetry (i.e.: symmetry of the coating of the genome) icosahedral (i.e.: spherical), helical (i.e.: rods), complex

  • Envelope +ve or –ve

  • Size (i.e.: measured in nanometres)


Note that DNA viruses always replicate in the nucleus (exception Pox viruses), whereas RNA viruses replicate in the cytoplasm (exception ≫ retroviruses). Most of the viruses present are ≫ RNA.
