Each capsid is composed of protein subunits called capsomeres made of one or more different types of capsomere proteins that interlock to form the closely packed capsid. B. protein and either RNA or DNA. The CroV capsid has a diameter of 3,000Å and a Triangulation number of 499. capsid [kap´sid] the shell of protein that protects the nucleic acid of a virus; it is composed of structural units, or capsomers. According to the number of subunits possessed by capsomers, they are called dimers (2), trimers (3), pentamers (5), or hexamers (6). Typically, a portion of the viral capsid will have a strong affinity to bind with one or another protein dotting the surfaces of one or another particular cell type. The binding of the viral capsid with that cell-surface protein serves as an admission ticket, easing the virus's invasion of the cell. D. protein, either RNA or DNA, and possibly lipid. 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. D. They Help The Virus Attach To The Host. In the present study, we have investigated the role of capsid phosphorylation in virus replication. Previous question Next question Transcribed Image Text from this Question. Virus-Like Particles. The protein capsid provides the second major criterion for the classification of viruses. Thus, capsomeres are the structural subunits of the viral capsid. 2. See the answer. It is the protein coat that surrounds the viral genome. Viruses formed from only a nucleic acid and capsid are called naked virus es or nonenveloped viruses. C. Lipid. But viruses have ways of tricking cells into letting them in. Each capsid is composed of protein subunits called capsomeres made of one or more different types of capsomere proteins that interlock to form the closely packed capsid. The shape of a viral coat has implications on how a virus infects a host. B. is called a capsid. The World of the Virus What is a virus? Capsid 3. Virus Capsid. Envelope 4. A capsid is the protein shell of a virus, enclosing its genetic material.It consists of several oligomeric (repeating) 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 proteins making up the capsid are called capsid proteins or viral coat proteins (VCP). This creates a small fortress around the genetic material, designed to protect it and to ensure that the virus gets to infect a host.The three basic capsid shapes are icosahedral, helical, and prolate; however, the shape of capsids can vary widely. It enables a virus to attach to hosts The capsid's main function is to protect the virus. This problem has been solved!
