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.
By incorporating part of a host cell membrane into its envelope, a virus can disguise itself and evade detection by the host's immune system. This camouflage allows the virus to enter host cells more easily without triggering an immune response, increasing its chances of successful infection.
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.
Virus host range refers to the range of organisms or cell types that a particular virus can infect. Some viruses have a broad host range and can infect multiple species, while others have a narrow host range and can only infect specific hosts. The host range is determined by factors such as the virus's ability to enter host cells and replicate within them.
The specific viral proteins on the surface of the virus determine its attachment to host cell membrane receptors. These proteins bind to complementary host cell receptors, allowing the virus to attach and enter the host cell.
The outer coat of a virus, also known as the viral envelope or capsid, protects the genetic material of the virus and helps the virus attach to host cells. It may also contain proteins or glycoproteins that allow the virus to enter host cells and evade the immune system.
The outer layer of a virus is called the capsid. Some viruses have an envelope over the capsid either one help the virus enter its' host.
Virus cannot replicate it self. It should enter into a host

envelop
A virus attaches to a host cell by recognizing and binding to specific proteins or receptors on the cell surface. This attachment is necessary for the virus to enter the host cell and begin the process of infection.
It has to enter the host DNA and "make" the host DNA make the virus parts. To do this the RNA that the virus contains has to be able to enter into the cell nucleus and take over the host DNA. It carries an enzyme called reverse transcriptase to complete this. See the link below for a very good idea of how it works:

it a part of a virus and takes over the host
The specific viral proteins on the surface of the virus determine its attachment to host cell membrane receptors. These proteins bind to complementary host cell receptors, allowing the virus to attach and enter the host cell.
It all depends on what you mean by your question. Both the host cell and the virus have proteins that must match for the virus to enter the cell. The more these match, the greater number of species of plants and animals that will be affected.
In a lysogenic infection, the viral DNA integrates into the host cell genome and remains dormant for a period of time. The host cell replicates with the viral DNA as part of its own DNA. Lysogenic infections can later transition into a lytic cycle, where the virus becomes active and replicates to produce new viruses.
