∙ 14y agoYes. Viruses contain a protein coat called a capsid. Inside this capsid will be DNA or RNA but never both. Viruses that contain RNA are called retroviruses. They also contain the enzyme reverse transcriptase that allows them to convert RNA into double-stranded DNA once it infects a cell.

∙ 11y agoMost viruses do have protein coats, but some do not, and consist only of nucleic acid.

Do all cells have cell membranes?
Yes, the cells of archaebacteria, bacteria, protists, fungi, plants and animals all have cell membranes. (Viruses have protein coats, not cell membranes and thus are not true 'cells'.) Thus indeed, all cells possess a cell membrane.
What structures are found in all viruses?
protein coat and nucleic acid
Are the outer coats of all viruses alike?
No. They come in different shapes and sizes and composition. That's why it's so hard to produce medications that will effectively treat viruses.
Do all living things have to make protein?
Yes. Viruses use the protein making organelles of the cell they take over.
Are all viruses made out of a cell or cells?
Viruses are made of nucleic acids; some also have a protein shell.
Why are viruses made of cells?
Viruses are made of cell parts because they cannot synthesize the materials without a host cell. Protein coats and the material for the nucleic acid are taken entirely from the host cell using its energy.
Is the spanish influenza virus single celled or mulitcellular?
Neither. Viruses do not have cells but are surrounded by protein capsids containing the viral DNA or RNA. Some viruses have glycoprotein coats that they take from the membranes of cells they preform lysis on.
Do all cells have cell membranes?
Yes, the cells of archaebacteria, bacteria, protists, fungi, plants and animals all have cell membranes. (Viruses have protein coats, not cell membranes and thus are not true 'cells'.) Thus indeed, all cells possess a cell membrane.
What structures are found in all viruses?
protein coat and nucleic acid
Are viruses made of?
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.
Are the outer coats of all viruses alike?
No. They come in different shapes and sizes and composition. That's why it's so hard to produce medications that will effectively treat viruses.
Do platelets have cell walls?
No, only Plant Cells have [to the exterior] cellulosic - protein coats. Animal Cells have glycosyl - protein coats.
Where is the protines of a virus located?
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.
Do all living things have to make protein?
Yes. Viruses use the protein making organelles of the cell they take over.
What basic structure do viruses share?
Unlike prions and viroids, viruses consist of two or three parts: all viruses have genes made from either DNA or RNA, long molecules that carry genetic information; all have a protein coat that protects these genes; and some have an envelope of fat that surrounds them when they are outside a cell. Viroids do not have a protein coat and prions contain no RNA or DNA. In short, just say that all viruses have a protein coat and either DNA or RNA.
Do viruses have a protein coat?
no
