1) it protects the nucleic acid from digestion by enzymes,
2) contains special sites on its surface that allow the virion to attach to a host cell
3) provides proteins that enable the virion to penetrate the host cell membrane and, in some cases, to inject the infectious nucleic acid into the cell's cytoplasm.

What is the protein coat that surounds a virus called?
The envelope.
What do you call the protein shell of a virus?
A capsid is the protein shell of a virus. It consists of several oligomeric structural subunits made of protein called protomers. The observable 3-dimensional morphological subunits, which may or may not correspond to individual proteins, are called capsomeres. The capsid encloses the genetic material of the virus.
A viral capsid is composed of?
it is composed of individual morphological units called capsomers.
Do viruses have a protein coat?
no
What is the nucleic acid core in a virus called?
the "core" of a virus is the nucleic acid (either DNA or RNA) that makes up the viral genome. this core contains all the genetic information of that virus, and is enclosed within the protein coat known as the capsid.
What is the function of a virus' capsid?
the protective protein coating
What are the three types of capsid?
helical capsid, icosahedral capsid and polyhedron capsid.
What is the outer layer of a virus composed of?
Outer layer of a virus is called a capsid. It is the shell of protein which protects the nucleic acid, the brain of a virus. Capsid is composed of individual morphological units called capsomers.
What is the function of virus head?
the nucleic acid and capsid of virus are in the head and they help also grow the virus
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 are the spikes and what is their function?
A part of the viral envelope/ capsid which are proteins is known as spikes. They help evade the defenses of the host cell are obtained from their protein.
What is the potein coat that surrounds a virus?
This coat is called a capsid. Sometimes these have a lipid envelope.
Do viruses feature a capsid?
no
What is responsible for the flu?
influenza capsid
What protect the DNA of a virus?
Capsid
What is the outer covering of bacteria?
capsid
What is a viruses coat called?
Capsid.
