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

Correct. For APEX it is, A protective shell around a virus.
This coat is called a capsid. Sometimes these have a lipid envelope.
The capsid. Made of protein, and sometimes various types of proteins.
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.

It surrounds the virus. Once the invading cell is inside the phagocyte it is killed by enzymes.
The Southern Ocean surrounds the Antarctic continent.
The Mediterranean Sea surrounds Cyprus
there is no sea that surrounds Illinois.
