Most RNA viruses carry RNA-dependent RNA polymerase (RdRp) enzyme, which is responsible for replicating the viral RNA genome within host cells. This enzyme plays a crucial role in the viral life cycle by synthesizing complementary RNA strands from viral RNA templates.

What two biomolecules can carry the genetic information for a virus?
The two biomolecules that can carry the genetic information for a virus are DNA (deoxyribonucleic acid) and RNA (ribonucleic acid). Viruses can have either DNA or RNA as their genetic material, which carries the instructions for the virus to replicate inside host cells.
What kinds of enzymes can be found within the virions of specific viruses?
Enzymes commonly found within the virions of specific viruses include polymerases (like RNA-dependent RNA polymerase), proteases (like HIV protease), and integrases (like HIV integrase). These enzymes play crucial roles in viral replication, maturation, and integration into host cells.
Viroids differ from viruses by what?
Viroids differ from viruses in that they are composed of a single-stranded circular RNA without a protein coat, while viruses have genetic material made of DNA or RNA enclosed in a protein coat. Viroids also do not encode proteins, relying on host enzymes for replication, whereas viruses typically encode proteins that contribute to their replication.
What is the difference between DNA viruses and RNA viruses?
DNA viruses contain genetic material in the form of DNA, while RNA viruses contain genetic material in the form of RNA. DNA viruses replicate in the host cell's nucleus, while RNA viruses replicate in the host cell's cytoplasm. DNA viruses tend to have lower mutation rates compared to RNA viruses.
Is polymerase and replicase are the same?
Polymerase and replicase are similar but not the same. Polymerase is a more general term referring to enzymes that synthesize polymers, while replicase specifically refers to enzymes involved in replicating RNA viruses by copying RNA into new RNA strands. replicase is a type of polymerase.
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.

Is RNA or DNA most important to virus?
Some viruses move RNA, some DNA; but RNA is more common.
Are enteroviruses RNA viruses?
Yes, enteroviruses are RNA viruses belonging to the Picornaviridae family. Their genome is composed of single-stranded RNA.

Viroids also do not encode proteins, relying on host enzymes for replication, whereas viruses typically encode proteins that contribute to their replication.
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.
How does viruses classificate?
DNA and RNA viruses.
