What two biomolecules can carry the genetic information for a virus?
DNA and RNA. Viruses that use RNA often have to have enzymes that convert the RNA to DNA.
What do you call molecules that carry out most cell function?
protiens
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.
RNA polymerase is an example of a?
Enzymes?
What is ssRNA-RT viruses?
These are the retro single-stranded RNA. These viruses make DNA from RNA using an enzyme called reverse transcriptase. One of the most famous example of the ssRNA-RT virus is the HIV virus.
What are the four ways to name a virus?
Major groups of viruses are distinguished first by their nucleic acid content as either RNA or DNA viruses. Subsequent subdivisions are based largely on other properties of nucleic acids. The RNA viruses can be single-stranded (ssRNA) or double-stranded (dsRNA), although most are single-stranded. Because most eukaryotic cells do not have the enzymes to copy viral RNA molecules, the RNA viruses must either carry the enzymes or have the genes for those enzymes as part of their genes. Like RNA viruses, DNA viruses can also occur in single-stranded or double-stranded form.

What is inside a virus cell apart from a RNA?
First, viruses don't have cells. A virus contains RNA or DNA inside a coating of proteins and sometimes lipids. Some viruses also carry enzymes to help in hijacking a cell.
What kind of genetic material do viruses have?
The genetic material that viruses have is RNA. Viruses are unable to truly carry out the processes associated with holding their own DNA.
Are enzymes fat?
No, most enzymes are proteins, some of which are "decorated" with sugars. A few enzymes are composed of RNA.

Are enteroviruses RNA viruses?
All enteroviruses are RNA viruses
Is RNA or DNA most important to virus?
Some viruses move RNA, some DNA; but RNA is more common.
If there is no restriction enzyme in eukaryotes how the proliferation of virus is restricted in eukaryotes?
They use a different mechanism: RNAi short of RNA interference, cleaves the virus genome (usually double stranded RNA) and destroys any strand that is complementary to the viral genome. -eukaryotic viruses are usually RNA viruses so they eukaryotes don't really restriction enzymes to protect against viruses.
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 viruses have Rna in their core rather than Dna?
They are called Rna viruses. Rna retro-viruses are a different and somewhat more complex matter.
Are enzymes usually proteins?
yes, most are. But some can be made of RNA.
