capsid 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.

What are capsomeres?
Capsomeres are the individual proteins that make the capsid - the protective protein coat around a virus's nucleic acid. Some capsomeres can be composed of a single protein or mosaic. Capsomeres/Capsids come in a variety of shapes (helical, polyhedral, enveloped, complex)
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.
Why would a drug that damages capsids help treat a viral infection?
capsids prevent viral infections apex they stop viral infections from reproducing
How do viruses attach to host cells?
Viruses attach to living cells by binding to the cell receptors. The receptor site is very much like a jig-saw puzzle and the virus must be shaped to fit the site and to lock in. The virus first sticks to the cell membrane of the host cell. The virus then inserts its DNA/RNA into the cell's cytoplasm. Once inside the host cell, the virus is uncoated, i.e. its capsid is dispersed, exposing the DNA/RNA. The DNA/RNA then takes over the host cell. The virus makes the cell produce new viral DNA/RNA and new capsomeres (proteins make up the capsid). The nucleic acid and the capsomeres are assembled in the cell to make new virus particles which escape from the cell. The cell might lyse and release new viruses to infect other cells. Examples of viral infection are cold sore, measles and chicken pox.
Which substance is a family of proteins whose specialty is fighting viruses by slowing or stopping their multiplication?
Interferons are a family of proteins that specialize in fighting viruses by slowing or stopping their multiplication. They are produced by the body in response to viral infections and help to boost the immune response against viruses.

What is mean by spike and capsomere?
A spike refers to a protein structure found on the surface of viruses, particularly enveloped viruses, that facilitates attachment and entry into host cells. Capsomeres are the individual protein subunits that assemble to form the capsid, the protective protein shell of a virus. Together, spikes and capsomeres play crucial roles in a virus's ability to infect host organisms and evade the immune system.
What is the the outer protein coat of a virus called?
It is called the capsid, and is usually composed of separate sub-units called capsomeres.
An icosahedron is composed minimally how many capsomeres?
12

List and describe the structural components of viruses?
Infectious particles consisting of nucleic acid encased in a protein coat and, in some cases, a membranous envelope. The smallest viruses are only 20 nm in diameter. The genome of viruses may consist of double-stranded DNA, single-stranded DNA, double-stranded RNA, or single-stranded RNA, depending on the kind of virus. Lack the enzymes for metabolism and the ribosomes for protein synthesis. Identify host cell (needed for reproduction) by a lock and key type system of outer proteins.
How are viruses good for humans?
the viruses help the immune system adapt and get stronger
How vaccines can help the body's natural defenses against the viruses?
This is how vaccines help the body's natural defenses against viruses: -because vaccines contain weak and dead viruses -this can help our immune system to recognize and adapt to it -so this will not be the problem for it if later on this type of viruses threat us Hope this help Vipha
How does sneezing and coughing protect the body from viruses?
They help to expel the viruses caught in the respiratory mucus.
Why would a drug that damages capsids help treat?
capsids prevent viral infections apex they stop viral infections from reproducing
Are viruses responsible for influenza?
Yes, viruses are responsible for influenza. That's why antibiotics don't help when you have the flu.
Why do antibiotics do not help teat viral infections?
Antibiotics treat bacterial infections, they have no affect on viruses. Vaccinations treat viruses.
