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 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 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 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 are the three types of capsid?
The three types of capsid are helical, icosahedral, and complex. Helical capsids have a cylindrical shape, icosahedral capsids have a polyhedral shape with 20 equilateral triangular faces, and complex capsids have a combination of both helical and icosahedral elements.
What is the potein coat that surrounds a virus?
This coat is called a capsid. Sometimes these have a lipid envelope.
What is the function of the capsomere?
Capsomeres are protein subunits that make up the capsid, which is the protein coat surrounding a virus. They help in the assembly of the capsid structure and protect the genetic material of the virus. Capsomeres also aid in the attachment of the virus to host cells during infection.
What is another name for protein coat?
Another name for a protein coat is a "capsid." The capsid is the protein shell that encases and protects the genetic material of viruses, playing a crucial role in their structure and function. It is composed of protein subunits called capsomers, which assemble to form the protective layer around the viral genome.
What are three functions of the capsid?
Protection: Capsid provides structural support and protection to the viral genome inside. Recognition: Capsid helps the virus recognize and attach to host cells for infection. Packaging: Capsid assists in packaging and organizing the viral genetic material during assembly and release.
What is the nucleic acid of a virus stored in?
The nucleic acid of a virus is stored in its viral capsid or envelope. The capsid or envelope protects the genetic material of the virus and helps it enter host cells to replicate.
Does H5N1 has a capsid or protein coat?
Yes, H5N1 is an influenza virus, which means it has a protein coat called a capsid surrounding its genetic material. The capsid helps protect the virus and enables it to infect host cells.
What is responsible for the flu?
influenza capsid
