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?
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.
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 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 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 DNA and RNA enzymes?
No, DNA and RNA (of which there are several types) are nucleic acids. All enzymes (if one adheres to the strict definition of the term) are proteins. Proteins are made of sequences of amino acids (coded for by nucleic acid genome) joined by peptide bonds or are polypeptides until they adopt their functional shape i.e. become enzymes and can act on specific substrate molecules. DNA is the genetic code (i.e. 'the stuff of genes') for most organisms, some viruses have an RNA genome. Summary - DNA/RNA contain the instructions to build proteins.
