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 is the name of the protein that surrounds the virus?
a capsid
What is the potein coat that surrounds a virus?
This coat is called a capsid. Sometimes these have a lipid envelope.
What is the protein coat the surrounds a virus call?
The protein coat surrounding the nucleic acid of a virus is called the capsid. These are broadly classified according to their structures. Helical (cylindrical) and icosahedral (spherical) are the most common types.
What surrounds the capsid and helps the virus enter the cell?
envelope
What is bacteriophage capsid?
Correct. For APEX it is, A protective shell around a virus.
What surrounds a virus?
I take it that you meant to ask what surrounds the genome of the virus. The genome of the virus (be it DNA or RNA) is enclosed within the capsid shell. The capsid shell is made by the oligomerisation of capsid proteins in a specific organised manner. The genome together with the capsid is termed as nucleocapsid. Sometimes the nucleocapsid is surrounded by a phospholipid membrane (of host origin) called the envelope. The viruses which have an envelope are called envelope viruses eg., Chikunguyna virus, Rabies virus, HIV and the viruses without an envelope are called naked viruses eg., Poliovirus, Rotavirus
What is a membrane surrounding the capsid of a virus?
envelop
The capsid of a virus is the?
the protection of a cell
What does surrounds the hereditary material of a virus?
The capsid. Made of protein, and sometimes various types of proteins.
What part of a virus does not enter the host?
Generally, the protein coat that surrounds the viral genetic material and any reverse trascriptase enzymes. This capsid stays outside the cell attacked while the genetic material and whatever else is needed is injected into the cell or the capsid merges with the cell membrane and the vital viral material enters the cell.
What is the name of the membrane that surrounds the nucleus?
cell membrane
The membrane that surrounds the nucleus are called the?
perinuclear membrane
