Viruses are composed of two main parts: an outer protein covering called a capsid and an inside core of either DNA or RNA. Not both DNA and RNA.
Some of these have an envelope over the capsid. The ones that do not are said to be naked. The proteins in the capsid allow the virus to attach to the "docking stations" proteins of the host cell.
The naked viruses are more resistant to changes in the environment.
A virus can have one of three structures. These are:
Helical virus. A helical virus is rod- or thread-shaped. The virus that causes rabies is a helical virus.
Icosahedral virus. An icosahedral virus is spherically shaped. Viruses that cause poliomyelitis and herpes simplex are icosahedral viruses.
Polyhedral virus.

What are the three types of fold structures in the Earth?

What are the two main structures of a virus?
Viruses have a particular character that they need a living host to survive or they cannot otherwise live. Generally viruses have a capsid which has its viral RNA enclosed in it. Capsid is covered by thick membrane.
Which of the three main types of microbes are the smallest?
Viruses are the smallest of the three main types of microbes, which also include bacteria and fungi. Viruses are much smaller than bacteria and fungi and are considered acellular, as they cannot survive or replicate without a host cell.
Which is one of the three domains viruses Animalia Protista Eukarya?
Viruses are not classified within any of the three domains of life, which are Bacteria, Archaea, and Eukarya. They do not fit into the domains of Animalia or Protista, as they are acellular entities that require a host cell to replicate and do not possess cellular structures. Instead, viruses are considered separate biological entities.

What 2 structures do all viruses have?
All viruses have nucleic acid and a protien coat called a capsid
Is viruses a producer or consumer?
Neither - viruses do not eat. There are debates about whether viruses are a form of life, or organic structures that interact with living organisms.
