Viruses dont have a cell membrane. Instead, they have a protein sheath.
If you mean what are viruses then they are nonliving strands Rna surrounded by a protein coat
interferon
No, animal cells do not have a protein coat. Only viruses have a protein coat.
Antibodies
interferon
Reverse transcriptase.
Viruses are surrounded by a protein coat called a capsid, which protects their genetic material. Some bacteria have an outer protein coat called a capsule, which provides protection and helps them adhere to surfaces.
Because viruses can not reproduce or produce protein without a host cell
protein, nucleic acid /\All viruses are made up of a core of genetic material ... nucleic acid, which is either DNA or RNA. This is surrounded by a protein coat.
When we talk about the anatomy of viruses we can only talk about the DNA or RNA or the protein jacket, as that is all there is to them. The protein is in the protein jacket.
