Are all viruses made of DNA
Viruses are smaller and simpler in construction than unicellular microorganisms, and they contain only one type of nucleic acid—either DNA or RNA—never both.
Are viruses DNA or RNA
Viral families are grouped based on their type of nucleic acid as genetic material, DNA or RNA 6. DNA viruses contain usually double‐stranded DNA (dsDNA) and rarely single‐stranded DNA (ssDNA). These viruses replicate using DNA‐dependent DNA polymerase. RNA viruses have typically ssRNA, but may also contain dsRNA.
How are animal viruses classified
Animal viruses can be classified by the nature of the nucleic genome (ie, DNA or RNA). In addition, viruses are often called by their morphological features. For instance, according to the existence of envelope, it can be called either an enveloped virus or naked (nonenveloped virus).
What is the genome of the animal virus
Animal virus genomes consist of either RNA or DNA, which may be single-stranded or double-stranded. Animal viruses may use a range of strategies (including some surprising and bizarre ones) to copy and use their genetic material, as we'll see in sections below.
Can viruses steal DNA
Scientists already know that viruses can steal DNA from their hosts. This is true for both viruses that infect eukaryotes — creatures with a nucleus in their cells — and those that infect bacteria. But viruses usually only have segments of DNA similar to their direct host.
Why do viruses not have DNA
This is because viruses do not have the tools to replicate their genetic material themselves. More recently, scientists have discovered a new type of virus, called a mimivirus. These viruses do contain the tools for making a copy of its DNA.
Why can’t viruses have both DNA and RNA
Answer and Explanation:
The genetic material in viruses is either RNA or DNA. It is not possible for a virus to contain both RNA and DNA. This is because (biologically speaking), there doesn't seem to be any need for it. As containing either of them gets the job done for a virus particle.
Are viruses living or nonliving
So were they ever alive Most biologists say no. Viruses are not made out of cells, they can't keep themselves in a stable state, they don't grow, and they can't make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms.
What are animal viruses mostly
Animal virus types include: double stranded DNA, single stranded DNA, double stranded RNA and single stranded RNA. Thus, the correct answer is option C. Was this answer helpful
What is the largest animal virus
Discovery of the Giant Mimivirus. Mimivirus is the largest and most complex virus known.
What is the largest animal DNA virus
Discovery of the Giant Mimivirus. Mimivirus is the largest and most complex virus known. Is it an evolutionary bridge between nonliving viruses and living organisms, or is it just an anomaly Viruses are small and fairly simple.
What is an example of an animal DNA virus
Companion animals such as cats, dogs, and horses, if not vaccinated, can catch serious viral infections. Canine parvovirus 2 is caused by a small DNA virus, and infections are often fatal in pups. The emergence of the parvovirus in the 1970s was the most significant in the history of infectious diseases.
Can a virus destroy DNA
It is apparent, however, that many RNA viruses can also induce significant DNA damage, even in cases where viral replication takes place exclusively in the cytoplasm.
Why viruses aren t alive
Most biologists say no. Viruses are not made out of cells, they can't keep themselves in a stable state, they don't grow, and they can't make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms.
Do all viruses only have RNA
Definition. A virus is an infectious microbe consisting of a segment of nucleic acid (either DNA or RNA) surrounded by a protein coat.
Do all viruses have DNA RNA
All viruses have genetic material (a genome) made of nucleic acid. You, like all other cell-based life, use DNA as your genetic material. Viruses, on the other hand, may use either RNA or DNA, both of which are types of nucleic acid.
Is A virus A Parasite
Viruses are small obligate intracellular parasites, which by definition contain either a RNA or DNA genome surrounded by a protective, virus-coded protein coat. Viruses may be viewed as mobile genetic elements, most probably of cellular origin and characterized by a long co-evolution of virus and host.
Are viruses plants or animals
Viruses occupy a special taxonomic position: they are not plants, animals, or prokaryotic bacteria (single-cell organisms without defined nuclei), and they are generally placed in their own kingdom.
What is unique about animal viruses
Animal viruses contain only one kind of nucleic acid, either DNA or RNA. To replicate, animal viruses divert the host cell's metabolism into synthesizing viral building blocks, which then self-assemble into new virus particles that are released into the environment.
What is the most legendary virus
Mydoom
Mydoom. Mydoom is arguably the worst malware in history, causing more than $38 billion worth of damages in 2004. Like Sobig, it was another type of mass mailing computer worm that stole email addresses from infected computers and sent itself to those addresses.
What is the smallest virus in the world
adenovirus
AAV is the smallest DNA virus with an average size of 20 nm. AAV was discovered in 1965 as a defective contaminating virus in an adenovirus stock (Atchison et al., 1965).

AAV is the smallest DNA virus with an average size of 20 nm. AAV was discovered in 1965 as a defective contaminating virus in an adenovirus stock (Atchison et al., 1965).
Do giant viruses exist
Mimivirus is the largest virus ever discovered. Giant viruses had been known for a few years, many of them in a group termed nucleo-cytoplasmic large DNA viruses (NCLDVs).
What do animal viruses contain
There are several types of animal viruses. They are commonly grouped into families according to the type of genetic material present in the virus. Animal virus types include: double stranded DNA, single stranded DNA, double stranded RNA and single stranded RNA. Thus, the correct answer is option C.
Do animal viruses replicate
A small infectious agent that is unable to replicate outside a living animal cell. Animal viruses infect animals and require animal cells as their host.
