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 lipid envelopeover 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.
Some naked viruses include poliomyelitis, warts, the common cold, chickenpox, shingles, mononucleosis, herpes simplex (cold sores), influenza, herpes viruses and HIV (AIDS).
Some enveloped viruses include norovirus (stomach bug), rotavirus and human papillomavirus (HPV).
The envelope can be damaged by freezing temperatures, chlorine, and phenol. If damaged the virus cannot infect.

Why do you call naked virus?
A naked virus has no lipid "coat".
A virus's DNA and RNA is surrounded by an?
A protein coat called a capsid.
Are viruses made of protein and lipid membranes?
A virus particle is composed of a nucleic acid that is surrounded by the capsid (which is the protective layer that is made out of protein). Some viruses can have lipid envelope however, not all viruses have a lipid envelope.
What is the potein coat that surrounds a virus?
This coat is called a capsid. Sometimes these have a lipid envelope.
What is role of virus in making vaccine?
The most common role of a virus in making vaccines is injection of a live weaken form of the virus. This virus will reproduce poorly once inside the body.
What is the role of the role of the lipid droplet in a chloroplast?
Lipids can store much energy.Excess starch are turned into lipids and stored.
What is the the outer protein coat of a virus called?
It is called the capsid, and is usually composed of separate sub-units called capsomeres.
How do you classify a virus?
Nature of the nucleic acid in the virionSymmetry of the protein shellPresence or absence of a lipid membraneDimensions of the virion and capsid
What does the liver play role in protein metabolism?
The liver has a central role in lipid metabolism. The liver produces bile, which is required for efficient intestinal fat absorption. The post-absorptive stages of metabolism occur from the lipid absorption in the intestines.
What is budding virus?
Some viruses have a lipid envelope and when the leave the cell, they do so by budding off rather than just busting out.
How large is a rhinovirus?
The spherical virus particles have a diameter of 50 to 70 nm and are covered by a lipid membrane. There are prominent "spikes" of 6 nm. Inside the lipid envelope is a capsid of 40 nm in diameter.
What role does a host cell play the formation of a virus?
reproduction engine
