Yes, that is correct - some viruses have RNA, others DNA.

Some organisms use singlestranded rather than doublestranded DNA In these organisms which enzyme would probably not be needed for DNA replication?
Some viruses have single stranded DNA molecules. These viruses do not have the machinery to synthesise the DNA on their own. They insert their DNA in a living cell where the DNA synthesis takes place.
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.
What are antiretroviral drugs?
Antiretroviral drugs inhibit the reproduction of retroviruses--viruses composed of RNA rather than DNA.
Hersheys and chases experiment led to the conclusion that?
DNA is the hereditary molecule in viruses.
Do all organisms have DNA?
Yes. DNA is the fundamental blueprint for all life on Earth.That depends on your definition of Life.Are viruses alive? Some say yes and some say no. Some viruses have DNA, and some only have RNA. So if you consider viruses a form of life, then some do not have DNA. RNA virus examples are SARS and Hepatitis. If you don't consider viruses alive, then yes, all forms of life (that we know of) higher than a virus contains some form of DNA. You can find out more at the link below.
Why rna virus is more mutant than dna virus?
during replication RNA-polimeraze it make a lot of erros.In this ways RNA viruses it mutate faster than DNa viruses.
How do animal viruses differ from bacterial viruses?
retro virus = any of a family of single-stranded RNA viruses having a helical envelope and containing an enzyme that allows for a reversal of genetic transcription, from RNA to DNA rather than the usual DNA to RNA, the newly transcribed viral DNA being incorporated into the host cell's DNA strand for the production of new RNA retroviruses: the family includes the AIDS virus and certain oncogene-carrying viruses implicated in various cancers.
Is DNA usually single-stranded?
DNA is double stranded Except in bacteria and some viruses and chloroplast and mitochondrial DNA
What does some disease causing viruses have instead of DNA?
RNA
Does viruses contain RNA?
Some viruses contain RNA; these are known as retroviruses. Others contain DNA.
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.
Is RNA or DNA most important to virus?
Some viruses move RNA, some DNA; but RNA is more common.
