Assuming you mean prokaryotic cells... Many viruses replicate use DNA or RNA in their genetic structure. Prokaryotic cells replicate by translating their DNA into RNA and then transferring it back into DNA. Many viruses hook into this system and use the prokaryotic replication to make copies of their own DNA or RNA.
Otherwise, many viruses replicate within prokaryotic cells in a parasitic relationship, using the genetic material, energy and parts of the cell to replicate their own genetic material and multiply or just to hide until they are ready to replicate.
what does a eukaryotic cell and a virus have in common
Nucleic acid, some proteins, and ability to reproduce. These similarities are also present in eukaryotes.
Both can be pathogenic (disease causing) and both elicit an immune response,
Neither have a membrane-bound nucleus.
They do not have, anything in common.
The cell wall is a common feature to prokaryotic and plant cells.
There is no "best" example because any one prokaryotic cell is equally prokaryotic as the next. The most common example would probably be E. coli.
Prokaryotic .
Flu is neither eukaryotic nor prokaryotic. It's a virus.
A eukaryotic plant would have a cell wall, plasma membrane, plasmodesmata, chloroplats, mitochondria, nucleus, ribosomes, Golgi body etc. A nonphotosynthetic prokaryotic would have a nucleus. Prokaryotic is simple, one-celled. No chloroplasts, mitochondria etc.
I will arrange these items in order; largest to smallest. eukaryotic cell----prokaryotic cell---virus Proteins---lipids ( I would not swear by this second answer )
What a cell and a virus have in common is the RNA or DNA. The virus can be either a RNA virus or a DNA virus.
A Eukaryotic Cell MUST contain a nucleus. A Prokaryotic Cell MUST NOT have a nucleus. A non-cell would be a virus.
The cell wall is a common feature to prokaryotic and plant cells.
cell membranes
There is no "best" example because any one prokaryotic cell is equally prokaryotic as the next. The most common example would probably be E. coli.
Thousands of viruses can fill one cell, either eurokaryotic of prokaryotic.
prokaryotic cells most likely bacteria or virus, etc.
virus??? Prokariotic cells, as bacteria, etc.
prokaryotic cell
prokaryotic cells
A prokaryotic cell (e.g. a bacterial cell).
