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
a capsid
This coat is called a capsid. Sometimes these have a lipid envelope.
When a white blood cell surrounds a virus, it typically engulfs the virus through a process called phagocytosis. The white blood cell then forms a vesicle around the virus, trapping it inside. Enzymes within the cell break down the viral particles, neutralizing the threat. This action helps to eliminate the virus from the body and triggers an immune response to protect against future infections.
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.
Correct. For APEX it is, A protective shell around a virus.
The envelope.
Enveloped viruses do have a membrane that they got from their host. All other viruses do not.
The capsid of a virus is surrounded by an envelope, which is derived from the host cell membrane during the viral replication process. This envelope contains viral glycoproteins that help the virus attach to and enter into host cells.

It surrounds the virus. Once the invading cell is inside the phagocyte it is killed by enzymes.
A virus is a microorganism that has a protein coat, also known as a capsid, which surrounds its genetic material. The protein coat helps protect the viral genome and assists in the virus' ability to infect host cells.
Every virus has two main parts: a protein coat called capsid that surrounds and protects the genetic material, and the genetic material itself which can be DNA or RNA. The genetic material contains the instructions needed for the virus to replicate and infect host cells.
