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:
In humans, genetic variations are caused because humans reproduce by a sexual life cycle which is termed as meiosis. In such a life cycle, the offspring receives half the chromosomes from the mother and half from the father. Crossing over and random assortment of chromosomes are two phenomenons which occur during meiosis. Due to these two phenomenons, genetic variations are caused.
During crossing over, the exchange of DNA segments between the homologous chromosomes takes place which brings about the genetic variations.

Eccrine glands are a part of the integumentary system.
Answer:
they are all a type of biome
Explanation:
<span>If you were given the AMINO ACID sequence, you could come up with a working DNA sequence, but even though this sequence may still make the same protein, it may not be the same DNA sequence that the original protein was coded from. This is due to the fact that there 64 different combinations for the four bases in DNA (A, T, C, & G), but only 20 amino acids to code for, therefore there's going to be overlap and there will be different codons that code for each amino acid </span>
