Answer:
Double-stranded DNA
Explanation:
If a virus requires to transport its genome in the nucleus to produce viral protein then the viral genome content must be DNA. This DNA of the virus will use the RNA polymerase of the host cell and will first convert into mRNA in the nucleus.
Then the mRNA of the virus will come out of the nucleus because the protein synthesis takes place outside the nucleus and in the cytoplasm. So in the cytoplasm by using host translational machinery the viral mRNA will code for viral proteins. So the correct answer is double-stranded DNA.
Answer AND Explanation:
<u>FACTORS THAT CAUSE GENETIC VARIATIONS</u>
- Crossing over. At the chiasmata during prophase I of meiosis, breakage may occur and exchange of genetic information may take place. New gene combinations which result in variations.
- Independent assortment. The arrangement of homologous chromosomes at the equator of the spindle during metaphase of the first meiotic division is random. These homologous chromosomes segregate into different daughter cells which contain different genetic combinations which brings about variation
- Fertilisation permits parental genes to be brought together in different combinations. This is the cause of variations in members of the same family.
- Mutation is the spontaneous change in the genetic makeup of an organism. These changes may be inherited by the offspring therefore beginning variation.
- Recycling, organic material
- Wasting less
- Water filtration, conserving water
- the materials used to make products of clothing

Viruses are referred to Agents since they don’t easily fit into categories of living things.
Viruses are composed of DNA and RNA and they can be referred to as
agents as they cause different diseases which is usually very difficult to
manage and treat.
Viruses don't perform the characteristics of living organisms, they lack cells
and isn't under Bacteria as they replicate only when in the body while
bacteria replicates anywhere.

Varicella Zoster Virus (VZV) causes varicella or chicken pox in humans. Chicken pox is generally found in children of 1 to 9 years of age but the virus can also infect the adults. The VZV infection becomes more complicated if it occurs in a pregnant woman.
Every pregnant woman should be checked for VZV infection. If a woman did not get affected with VZV will not have the antibodies against the virus. Such woman should be given varicella vaccine.
In a VZV infected pregnant woman the following symptoms can be seen such as fever, myalgia, malaise and painful skin rashes. The lesions or rashes first appear on the head and trunk that spreads to the lower parts of the body. The disease becomes complicated if pneumonia and encephalitis also occurs along with VZV infection.
