Answer: Viruses are composed of eight proteins. RNA. And ribosomes. Vi single stranded DNA. C. Double stranded DNA. And RNA. D. Single stranded RNA. A. E. RNA or DNA. Never both and a protein coat. It's a great answer. Here is e so virus has two components that all of them have nucleic acid and a protein caps it so this is their genetic material. It can be RNA or DNA. It can be single stranded or double stranded of Eva. But it's never a mixture of DNA and RNA. So it's one or the other and they have a protein caps it here the protein coats. So all viruses have these two components some also have a lipid envelope and those are called enveloped viruses. All of them have these two components. They don't have ribosomes. They need to use the host ribosomes translate their genes. There. I'm RNA is they may have single stranded DNA but they'll also have the protein caps it. And they could be R. N. A. Same for single stranded RNA. They could be single stranded DNA. Or double stranded DNA. And that MRS. For protein. And see it cannot be because this is a mixture of nucleic acids. And also another edition is they can have proteins that come along with them. For example. HIV will bring along reverse transcriptase inside the very um but they all at least definitely have RNA or DNA but not both. And a protein coat. All viruses will have that
