1-the viron particle consists
essentially of a genome enclosed in a capsid.
2-A virion has
both types of nucleic acids, both RNA for protein production and DNA to code
for ribosomes.
3-A virus can
replicate both in a living cell and a dead cell.
4- Viruses
are not susceptible to most of the conventional antibiotics.
5-All viruses
have one capsid.
6- capsomeres
are arranged in regular patterns and their numbers vary in different viruses.
7- Some
capsomeres are hollow, but most are solid.
8- In
helical viruses, the capsomeres and nucleic acid molecule(s) self-assembly as a
helix.
9-All animal viruses helical nucleocapsids are wound into a coil and enclosed within a lipoprotein envelope.T
