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".
What is the potein coat that surrounds a virus?
This coat is called a capsid. Sometimes these have a lipid envelope.
A virus's DNA and RNA is surrounded by an?
A virus's DNA and RNA are surrounded by a protein coat called a capsid. This capsid provides protection to the virus's genetic material and helps it to infect host cells. Some viruses also have an additional lipid envelope surrounding the capsid.
What is the lipid envelope?
The cell lipid envelopes allow some things to go in and some to come out but not all things. They are similar to the walls of your house. It has doors and windows in the wall just as the membrane does.
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 the outer protein coat of a virus called?
It is called the capsid, and is usually composed of separate sub-units called capsomeres.
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 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.
What is a polar lipid?
A polar lipid is a type of lipid molecule that contains a polar "head" region and a nonpolar "tail" region. They are important components of cell membranes and play a role in forming lipid bilayers that help regulate the passage of substances into and out of cells. Examples of polar lipids include phospholipids and glycolipids.
Is serotonin a lipid soluble compound?
No, serotonin is not a lipid soluble compound. It is a water-soluble neurotransmitter that plays a key role in regulating mood, sleep, and appetite.
What is a core virus made of?
A core virus is typically made up of a genome, which contains the virus's genetic material (DNA or RNA), surrounded by a protein coat called a capsid. Some viruses may also have an outer lipid envelope derived from the host cell membrane.
