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.
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.
What else can I help you with?
What is the membrane called that surrounds your heart?
Pericardium
What is the bag called that holds the cytoplasm in?
The membrane that surrounds the cytoplasm in a cell is called the cell membrane or plasma membrane.
What is tonoplast?
The cytoplasmic membrane that surrounds a vacuole of a plant cell. Also called vacuolar membrane.
Is nuclear membrane the same thing as cell mmbrane?
No, the nuclear membrane surrounds the nucleus in eukaryotic cells, while the cell membrane (plasma membrane) surrounds the entire cell to separate its internal environment from the external environment.
The outer coating of a cell is called a?
The outer coating of a cell is called the cell membrane. It is a thin, flexible barrier that surrounds the cell and controls the movement of substances in and out of the cell.
The membrane that surrounds the nucleus are called the?
perinuclear membrane
What is the membrane that surrounds the DNA called?
nucleus
What is the membrane called that surrounds your heart?
Pericardium
What is the bag called that holds the cytoplasm in?
The membrane that surrounds the cytoplasm in a cell is called the cell membrane or plasma membrane.
What is the name of the membrane that surrounds the vacuole?
It is called the vacuolar membrane.Sometimes it is referred to as the vacuole membrane. The membrane round the large central vacuole in plants it is also called the tonoplast.
The membrane that surrounds the embryo and is filled with fluids that cushions and protects the embryo is called the what?
The membrane that surrounds the embryo and is filled with fluids that cushions and protects the embryo is called the amniotic sac or amnion.
What is the phospholipid bilayer that surrounds and maintains integrity of a cell called?
The phospholipid bilayer that surrounds and maintains the integrity of a cell is called the cell membrane or plasma membrane. It acts as a barrier that controls the passage of substances in and out of the cell, allowing for the regulation of cellular activities.
What are the thin flexible envelope that surrounds a cell called?
cell membrane
What structure surrounds the cell membrane in a plant cell?
It is called the cell wall
What is tonoplast?
The cytoplasmic membrane that surrounds a vacuole of a plant cell. Also called vacuolar membrane.
What is the membrane that surrounds the cells?
this is the cell membrane made primarily of lipid molecules with proteins incorporated into it that aid in transport of molecules across the membrane
Is nuclear membrane the same thing as cell mmbrane?
No, the nuclear membrane surrounds the nucleus in eukaryotic cells, while the cell membrane (plasma membrane) surrounds the entire cell to separate its internal environment from the external environment.
