The protein coat or shell of a virus particle, surrounding the nucleic acid or nucleoprotein core

What are the parts of a hexagon virus?
A hexagon virus has a round shaped caspid but with six sides. Inside can be either RNA or DNA but not both.
How are viruses classified by nucleic acids capsid shape and the presense of the envelope?
The baltimore system of virus classification can be used to classify viruses based on nucleic acids. Caspid shape I'm not so sure of, but the ICTV system is a good starting point.
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.
What is the membrane called that surrounds a caspid?
Viruses are composed of two main parts: an outer protein covering called a capsid and an inside core of either DNA or RNA. Not both DNA and RNA.Some of these have an envelope over the capsid. The ones that do not are said to be naked. The proteins in the capsid allow the virus to attach to the "docking stations" proteins of the host cell. The naked viruses are more resistant to changes in the environment.Some naked viruses include poliomyelitis, warts, the common cold, chickenpox, shingles, mononucleosis, herpes simplex (cold sores), influenza, herpes viruses and HIV (AIDS).Some enveloped viruses include norovirus (stomach bug), rotavirus and human papillomavirus (HPV).The envelope can be damaged by freezing temperatures, chlorine, and phenol. If damaged the virus cannot infect.
What are 4 main parts of a virus?
A virus typically consists of genetic material (DNA or RNA), a protein coat called a capsid that encloses the genetic material, an envelope derived from the host cell membrane (in some viruses), and sometimes additional structures like spikes or tails for attachment and entry into host cells.
How can you tell whether the cell is animal bacterial or plant?
if a cell is a plant cell it will have a cell wall, a vacuole and chloroplasts. if it is an animal cell it will have none of these things. these are both eukaryotic cells. if it is a prokaryotic cell it will have no nucleus just a circle/tangle of DNA, it will most likely be a bacterium and have flagella or cillium, it may also be eclosed in a caspid.
