In a virus, the three functions of the capsid is to tightly pack the enzymes and genetic material, to protect the contents from degradation, and to prepare the contents for release upon interaction with a suitable host. This is the basis of the function of a spore.

1.) Protect viral genome
2.) allow virion to attach to host cell
3.) provides proteins to allow the virion to penetrate host cell
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.
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.
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.
A virus's DNA and RNA are surrounded by a protein coat called a capsid. This capsid provides protection to the virus's genetic material and helps it to infect host cells. Some viruses also have an additional lipid envelope surrounding the capsid.
No, prokaryotic cells do not have a protein capsid. Protein capsids are a characteristic feature of viruses, which are non-living entities that infect cells. Prokaryotic cells, such as bacteria, are living organisms that do not possess a protein capsid.
