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.
What else can I help you with?
What may contain DNA or RNA but not both?
Viruses can contain either DNA or RNA, but not both. However, some viruses may have both DNA and RNA at different stages of their replication cycle.
Does Virus contain both DNA and RNA?
Viruses can contain either DNA or RNA, but not both. DNA viruses have genetic material made of DNA, while RNA viruses have genetic material made of RNA. Some viruses have single-stranded genetic material, while others have double-stranded genetic material.
What genetic material is in both viruses and bacteria?
Both viruses and bacteria contain genetic material in the form of DNA or RNA. Viruses can have either DNA or RNA as their genetic material, while bacteria typically have DNA as their genetic material.
Viruses contain DNA and RNA true or false?
Yes. Although not both together, a virus contains a nucleic acid, either single stranded or double stranded DNA or RNA.
Does viruses contain RNA?
Some viruses contain RNA; these are known as retroviruses. Others contain DNA.
Why does a virus not have both DNA and RNA?
Because it doesn't use it's DNA or RNA to function, it uses it to inject into a cell and switch the cell's instructions to its own so the cell will make more viruses. Cells have DNA and RNA to tell the cell what to do, but viruses just do it naturally. Viruses have no use for both.
What are viruses genetic materia?
Viruses contain either DNA or RNA.
Is there anything that does not contain DNA?
Yes. Anything that isn't an organism will not contain DNA. For example, rocks do not have DNA. Additionally, some viruses have RNA instead of DNA although viruses would be covered by the first category mentioned.
Do both cells and viruses have genetic material?
Viruses do not contain DNA or RNA . . . they 'steal' those molecules from their host living cell.
Do virus have protein coat?
Yes. 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.
What are the two types of genetic material found in viruses?
The two kinds of genetic material that can be found in viruses is either going to be RNA or DNA either or you want find both in same virus, but what can happen is (Dogma - DNA to RNA they have an RNA to DNA step this usaully occurs in Retoviruses suh H.I.V..
What is the difference between DNA viruses and RNA viruses?
There are several differences for example; most DNA viruses use the DNA polymerases of of the host cell to synthesize new genomes along the templates provided by the viral DNA, in contrast to replicate their genomes, RNA viruses use virally encoded polymerases that can use RNA as a template. RNA viruses usually retain their RNA within capsids, whilst DNA viruses are less "packaged" usually retained within say a head, or a capsomere. The main difference of course, is that DNA viruses contain either a doubled stranded DNA (dsDNA) or a single stranded (ssDNA), and RNA viruses contain dsRNA or ssRNA. There are of course several other differences, but these are the ones I know of.
