Viruses with RNA as their genetic material are called retroviruses. They use the enzyme reversetranscriptase to transcribe their RNA genome into DNA, which is then inserted into the host's genome.

What is called the group of viruses having both dna and rna?
Reverse transcriptase is the name given to the group of viruses having both the RNA and DNA.
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 processes requires RNA?
protein synthesis, translation. and transcription. Some viruses contain RNA instead of DNA. These viruses have an enzyme called reverse transcriptase. The virus then uses the host cell to produce DNA from the RNA using reverse transcriptase.
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.
Most RNA viruses carry which enzymes?
reverse transcriptase. With this enzyme, the RNA viruses can make DNA using their RNA as a template.
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.
Is H1N1 influenza a retrovirus?
No it is not. Retroviruses are RNA viruses that can change their RNA into DNA for cell infection (example HIV). Influenza viruses are also RNA viruses, but they do not transcribe the RNA into DNA. Some people think the R in RNA stands for retrovirus, but it stands for ribonucleic acid.
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.
Do all viruses have protein coats?
yes
What is the only characteristics shared by living cells and viruses?
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. Living cells also contain DNA and RNA. These are the only thing shared by living cells and viruses.
Are enteroviruses RNA viruses?
All enteroviruses are RNA viruses
Does RNA virus have Reverse transcriptases in them?
The RNA viruses that contain reverse transcriptases are collectively called retroviruses among which are: HIV, human immunodeficiency virus (AIDS); RNA tumor viruses (leukemia)
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.
How does viruses classificate?
DNA and RNA viruses.
Does viruses contains genetic material?
All viruses have genes made from either DNA or RNA but they themselves don't have DNA. (Viruses use tRNA or mRNA or DNA as a tool for infecting host cells, but they they do not use either for their own internal bio-mechanics)
Does viruses contain RNA?
Some viruses contain RNA; these are known as retroviruses. Others contain DNA.
What is called the group of viruses having both dna and rna?
Reverse transcriptase is the name given to the group of viruses having both the RNA and DNA.
