a capsid
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.
The protein coat that surrounds a virus is called a capsid. It is composed of protein subunits called capsomers and serves to protect the viral genetic material while also aiding in the virus's ability to infect host cells. The capsid plays a crucial role in the virus's structure and function, helping to determine its shape and stability.
The envelope.
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.
Correct. For APEX it is, A protective shell around a virus.

The capsid. Made of protein, and sometimes various types of proteins.
Enveloped viruses do have a membrane that they got from their host. All other viruses do not.
Answer by Techsupportcapsid provides the second major criterion for the classification of viruses. The capsid surrounds the virus and is composed of a finite number of protein subunits known as capsomeres, which usually associate with, or are found close to, the virion nucleic acid.
The two main parts of a virus are Protein Coat and Nucleic Acid. The protein coat completely surrounds the nucleic acid and serves as a protective coating and aids in attachment of the the virus to the host cell. The nucleic acid can be either Deoxyribonucleic Acid (DNA) or Ribonucleic Acid (RNA).
