Viruses carry genetic material that they insert into our cells to make our cells stop doing what they normally do and start reproducing viruses, the genetic material is encoded with the information needed to reproduce that specific virus exactly.

Why do most viruses have a single strand genome while larger viruses have a double strand genome?
The larger are encoding hundreds more proteins and assembling more complex virions.
What is all the genetic information in one complete set of hereditary material?
All the genetic information in one complete set hereditary material is a genome. The genome is encoded with either DNA or many types of viruses and RNA.
All of the DNA in each cell of the body is called the?
blueprint cell
RNA viruses are also called?
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 are all DNA in one cell of an organism?
DNA is found (usually) in each cell of an organism in the nucleus or in an area called a nucleoid.
Are DNA genomes found in all organisms and viruses?
yes, but many viruses do not have DNA genome, but RNA genome.
What characteristics do scientists use to classify viruses?
their genome
Why do most viruses have a single strand genome while larger viruses have a double strand genome?

What contributes to antigenic shift in influenza viruses?
a segmented genome
What is the main way viruses replicate?
It depends on the nature of its genome
Where is a genome found?
It's encoded in either DNA or for many types of viruses, in RNA

What surrounds a virus?
I take it that you meant to ask what surrounds the genome of the virus. The genome of the virus (be it DNA or RNA) is enclosed within the capsid shell. The capsid shell is made by the oligomerisation of capsid proteins in a specific organised manner. The genome together with the capsid is termed as nucleocapsid. Sometimes the nucleocapsid is surrounded by a phospholipid membrane (of host origin) called the envelope. The viruses which have an envelope are called envelope viruses eg., Chikunguyna virus, Rabies virus, HIV and the viruses without an envelope are called naked viruses eg., Poliovirus, Rotavirus
All of the DNA in each cell of the body is called the?
blueprint cell
What are pro viruses?
A pro virus is a a complete viral genome which is incorporated in a host's genome. It is dormant while incorporated and therefore passed on to that cell's "offspring" and is waiting to be expressed at a later time.
Do viruses need light?
no,as we all know that these are intracellular parasites,they may be destroyed in presence of light.they genome may be altered in presence of light such as frame shift ar mutation.
If there is no restriction enzyme in eukaryotes how the proliferation of virus is restricted in eukaryotes?
They use a different mechanism: RNAi short of RNA interference, cleaves the virus genome (usually double stranded RNA) and destroys any strand that is complementary to the viral genome. -eukaryotic viruses are usually RNA viruses so they eukaryotes don't really restriction enzymes to protect against viruses.
